Description

METHOD AND APPARATUS FOR NAVIGATING LITERATED TEXT CROSS REFERENCE WITH RELATED APPLICATIONS This application claims the benefit of the Patent Application of United States Serial No. 60 / 469,534, filed on May 8, 2003, entitled "Navigational Aid for Searching Long Text Lists" (NAVIGATION AID FOR SEARCHING LARGE LISTS OF TEXT).

FIELD OF THE INVENTION The present invention relates to a method and apparatus for improving the search process of a specific article in a long alphabetized list when up and down scroll buttons are used in a portable electronic device or personal computer, and in particular , to improve the search speed of a specific article in a literate list.

BACKGROUND OF THE INVENTION Many portable electronic devices and personal computer type devices have a limited display size that can allow the deployment of only a limited number of lines of text. When searching for a particular file with the use of such a device, when the device includes a large number of files it can be a difficult challenge for the user. In the case of a hard disk drive based on a personal, digital audio player, such as an MP3 player, the device may contain from about three thousand (3000) to six thousand (6000) or even more songs or files from digital audio data. In current devices, buttons or up and down scrolling keys are widely used to navigate song titles up and down. The titles can be arranged in alphabetical order to help find a specific article. However, because there are thousands of items on the list it can take a long time with the use of a conventional method of posting to locate the song that is in the middle or at the end of the list. In order to try to improve this problem, several techniques have been developed in order to increase the speed of displacement as a function of the time that the scrollable keys are pressed up and down. It is an attempt to reduce the time it can take to scroll through the items on the list. As an example of the prior art in order to reduce the time needed to scroll through the list of items, the speed of travel will be accelerated while the key is held down. For example, a single press of the button / quick key (that is, less than 0.5 seconds), advances an item in the list. When the key is pressed and held for more than 0.5 seconds and up to 2.0 seconds, the list advances to five (5) items per second. When the key is pressed and held for more than 2.0 seconds and up to 4.0 seconds, the list advances up to ten (10) items per second. When the key is pressed and held for more than 4.0 seconds, the list advances to twenty (20) items per second. However, eventually, the scrolling becomes so fast that the text can not be read. Therefore, an upper limit must be set for the travel speed. When twenty (20) items per second are set as the upper limit, it will take five (5) minutes to scroll through six thousand (6000) items (ie, 5 minutes = 6000 items / 20 items per second / 60 seconds per minute). Also, when the key is released and pressed again, the process starts from the beginning. It is clear from the above that the current process to search or scroll through a long list of text in order to locate a particular article is rather time consuming and / or annoying.

Therefore, it is evident from the above description that what is needed is a more efficient way to search or scroll through a quantity of literate text. Therefore, it will also be evident from the above description that what is needed is a quick way to locate a text article through scrolling in a long list of alphabetized text. These and other needs are met with the application of the principles of the present invention and / or are incorporated in one or more forms and / or structures as shown and / or described herein.BRIEF DESCRIPTION OF THE INVENTION A method and / or apparatus is described which improves the search speed of a specific article in a list of alphabetized text during navigation up and down the list of alphabetized text. The method provides controlled navigation through the alphabetized list depending, for example, on the amount of time in which the user input is received or on which an appropriate button is activated, and / or list characteristics such as the number of Text articles by letter of the alphabet. The method can be implemented in a portable audio data player, a PC or in another electronic device. In one form, the present invention provides a method for navigating through a literate list of text articles that represent audio data files in an electronic device. The method includes (a) advancing and displaying the alphabetized list of text articles by a text article in response to the pressing of a key of a first duration; (b) advancing and displaying the alphabetized list of text articles at a predetermined speed of the text articles in response to the pressing of a key of a second duration; and (c) advancing and displaying the alphabetized list of text articles by text articles having an initial letter, which is the following in the alphabet in relation to the initial letter of the text article displayed at that moment in response to a pulsation of a third duration key. In another form, the present invention provides a digital audio data player. The digital audio data player includes: a data storage device for storing a literate list of text articles corresponding to a plurality of audio data files encoded in digital form, a display for displaying the alphabetized list of text articles , a first user input device for accepting user input, and a controller coupled with the data storage device, the display and the user's first input device to control the operation of the data storage device and the display in response to user input. The controller operates to (i) advance and display the alphabetized list of text articles by a text article in response to user input of a first duration through the user's first input device, (ii) advance and display the literate list of text articles by a predetermined speed of text articles in response to user input of a second duration through the user's first input device; and (iii) advancing and displaying the alphabetized list of text articles by the text articles that have the initial letter that is later in the alphabet in relation to an initial letter of a text article displayed at that moment in response to the entry of the user of a third duration through the user's first input device.

DETAILED DESCRIPTION OF THE INVENTION The embodiment described herein is not intended to be exhaustive or to limit the invention to the precise form set forth, rather it is intended to be used by persons skilled in the art. Figure 1 shows a block diagram of an electronic device represented as a portable audio data player 10, wherein the present invention can be used and / or incorporated. It should be appreciated that the portable audio data player 10 is only one example of the type of electronic device or component that can be used and / or incorporate the principles of the present invention. As such, the portable audio data player 10 represents other devices and / or components that use and / or incorporate the present invention, but not all of them are necessarily described. Other devices include personal computers (PC), music management software, hard drives and audio data players with flash memory, compact disc players, DVD players, PVR products and / or their like, where the user can navigate, move forward or move (in an up and down direction) through a list of text articles. As indicated, the method can be incorporated as a programming or software. The general arrangement and operation of the different elements of the portable audio data player 10 are described both generally and in the context of the present invention. However, the details of the different elements of the audio data player 10 are well known to those skilled in the art. The audio data player 10 comprises a microcontroller (controller or its like) 22 which controls the different elements and the general operation of the audio data player 10, including the transfer of data from the data storage 32, through the intermediate memory, and the digital audio decoder (DSP) signal processor 12. The microcontroller 22 includes a suitable amount of memory 23, for storing different groups or instruction programs for controlling the operation of the audio data player 10 including carrying out or implementing the principles of the present invention. As noted in more detail below, the method according to the principles of the present invention can be used with other types of devices or components that reproduce audio from a multitude of pre-recorded content, especially digital audio content, data and / or or files. The DSP 12 may be programmed to perform a variety of signal processing functions during playback of the selected audio data file, as well as segments or selective portions (i.e., audio attachments) of the audio data files. In this case, the functions that the DSP 12 performs during playback include, but are not limited to, the decoding of audio data files, volume control, digital sound equalization, and sample conversion. The DSP 12 also performs other functions necessary to implement the principles of the present invention, as well as other typical functions not necessarily described herein. In this respect, the DSP 12 includes an on-board memory 11, wherein the decoder files, audio data files, audio attachments, the equalizer mode selection and various other data required during playback are loaded. The decoder files comprise programs that control the decoding operations of the DSP 12, the audio data files include audio attachments that include data associated with the audio content. Both the audio data files and the decoder files can be stored in the data mc 32. The decoder file including the programs is transferred to the memory 11 of the DSP from the data storage 32. Alternatively, the decoder files can be stored in ROM 23, RAM 11 or other appropriate storage device of player 10. In addition, the decoder files and other system and program files can also be stored in an SDRAM 25, or other appropriate storage devices coupled with the DSP 12. Also, the microcontroller 22 and the DSP 12, as well as other elements within the player 10 can be incorporated within a single element, for example, within a single IC. The audio data and the decoder programs stored in the data storage 32 can be encrypted, which requires that the decoding program files and the audio data files be deciphered by the DSP 12 with the use of one or more decryption keys. The decryption keys can also be stored in the data storage 32 and can be securely linked to the particular storage device or to some encoded component of the audio data player 10, so that the audio data files encrypted for use in A particular audio data player can be deciphered and played only by that particular audio data player. As a selected audio file is decoded, the DSP 12 provides a decoded data stream to the digital to analog converter 14. The converter 14 D / A converts the digital output of the DSP 12 into an analog signal and provides the analog signal to the headphone amplifier 16 and the output line preamp 40. The analog signals are amplified and provided to an output line bushing 41 and to a bushing 17 of the hearing aids, both arranged in the housing 13 of the audio player 10. The audio player 10 is adapted to operate with the data storage 32. In this embodiment, the data storage 32 is a large data storage device, specifically a hard disk, which can be used to store several data files, including the encoded audio data files, the decoder files to control the decoding operation of the DSP 12, the text files of the playlist, the alphabetized text files of the content of the audio file, audio attachments and computer data files. The data storage device 32 may be in the form of a removable device, such as a compact flash card or a secure media card. A large amount of data can be quickly transferred between the data storage 32 and the microcontroller 22 through a data bus 33. The buffer 25 operates as a circular data buffer to prevent interruption of audio playback caused by a data transfer delay or other data transfer delay of the mobile data storage device. The audio player 10 has a display module or device 20 which is represented as an LCD display module. However, it can be appreciated that the type of deployment module may vary as appropriate. Figures 2 to 4 illustrate an exemplary embodiment of the display, buttons, switches, indicators and ports that may be arranged in the housing 13 of the audio data player 10, which are used as indicated here to carry out the principles of the present invention, such as, for example, selecting a list of audio data files or selecting the type of information to be displayed with respect to the list of audio files selected. One or more buttons constitute a user interface or user input device to allow the user to make the appropriate selections for the particular mode of the digital audio player. The user's input 26 (as illustrated in block form in Figure 1), comprises a plurality of buttons 44 (Figure 3), 46, (Figure 4), and 60-77 arranged in the housing 13 of the audio data player 10 to allow the user to classify and select the particular audio data files , create and / or select particular lists of audio data files grouped in various ways such as by title, artist, album, date, etc., move or advance through the list of audio files selected for playback, with the to control playback settings, select a group or collection of audio data files, select attribute preferences for playback of audio attachments, include or add identification data representative of an associated audio data file for an audio attachment reproduced at that time, preferably, but not necessarily, a selectable playlist, skip the inclusion of the identification data repres features of an associated audio data file for an audio attachment reproduced at that time, and / or other features and / or functions associated with a typical audio data player, as well as for the implementation of the present invention. The user input 26 may also comprise other input devices known in the art, for example, a keyboard, a voice activated touch keyboard, and on-screen touch input devices. Two multi-way switches comprise buttons 62 to 68. Functional softkeys are multi-function buttons whose function changes for various user interface menu displays. The audio data player 10 also includes a display 21 arranged in the housing 13. The display 21 displays the audio data files, the playlists and the audio attachment information stored in the data storage 32, the function of the programmable function keys 74-77 and the different status information associated with the audio data player 10, such as the playback state shown in Figure 2, as well as other higher level menus. The display 21 operates together with other components of the audio player 10 to display the text data of the audio files and / or the data with respect to the audio files such as the artist, title and / or their like which are stored. in the audio data player 10. This information is movable in the display 21 in accordance with the principles of the present invention. In Figure 2, the STOP / ON button 60 allows the user to stop playback and turn on or turn off the audio data player 10. The PLAY / PAUSE button 62 allows the user to start playback and pause playback. The button 62 can be moved in the UP, DOWN, RIGHT and LEFT directions and allows the user to move a highlight to the right or left when using the menu and to jump back to the previous audio data file or the audio attachment , or scan forward or backward in the current audio data file when playing music. Button 62 also allows the user to move to highlight up and down when the menu is used or when scrolling, advancing or navigating through the text list as a list of selected audio files presented in any form (ie , as a list of titles of audio files, such as a list of artists in the audio file, or similar). In addition, the button 62 is used as a user input to start and then control the navigation speed, scroll or advance through the text list in one direction. The control of the navigation speed is achieved by the length of time the user keeps pressed (presses or operates) the button 62 in the desired direction, the details and the different ways to implement this feature are described below. Other buttons, items, or even touch screen entries (not shown) may be used in place or in addition to the down arrow 66 button and up arrow 64 button. Referring still to Figure 2, the SELECT button 68 allows the user to select a highlighted item when moving or advancing (collectively, browsing) through the list of audio files. The mobile button 68 in the volume raising direction 69 increases the volume level of reproduction for the hearing aids 18 and the lowering volume 71 decreases the volume level. The mobile button 68 in the direction of MODE 70 allows the user to select a particular play mode, including NORMAL, REPEAT, REPEAT ONE, REPEAT ALL, RANDOM, REPEAT ALL RANDOM and creation modes of the playlist. CREATE LIST PLAYBACK and ADJUSTMENT OF AUDIO PREFERENCE SETTINGS. Programmable function keys 74-77 select the item from the menu that appears just above each button at the bottom of the display 21. Referring now to Figure 3, the POWER indicator 78 lights up when the audio player 10 is turned on. switched on. The LOAD indicator 79 is illuminated when the power source 47 is being charged. The DC IN socket 48 provides 5 volts DC from an AC adapter to turn on the audio data player 10. The RESET button 44 allows the user to reset all audio data player settings with factory default settings. Referring now to Figure 4, switch 46 OFF / LOCK allows the user to inactivate the buttons 60-77 when the switch 46 slides to the locked position. The OUTPUT LINE bushing 41 allows the user to connect the audio data player to a separate audio system. The hearing aid cap 17 allows the user to reproduce the decoded audio in the hearing instruments 18. The USB port 42 provides the connection of the audio data player 10 to a PC or other similar device with the use of a USB cable. In accordance with the principles of the present invention, the audio data player 10 also operates to provide controlled navigation through a list of text provided in the display 21 (displayed therein). It should be appreciated that although the present method is described as being implemented in an audio data player, the present method can also be applied in a PC (implemented as and / or in an audio file management software) and other components or devices that store and / or use the audio data files (audio files). In addition, the audio data player 10 performs many functions and includes many features that are not necessarily described here. Thus, the audio data player 10 has various modes of operation, such as retrieving audio data files, reproducing audio data files, creating lists or data of the user or their peers. Initially, the audio data player 10 is caused to be in a text search mode, an audio data file search mode, a list mode or a similar mode, where the text list as a list of alphabetized text, a library of lists, a group or collection representing audio data files or other identifying / representative information is provided to the display 21 through or in response to user input. The user can then navigate through the text list and select a particular article if desired. Navigation is typically represented by highlighting a single text article from a number of displayed text articles. This serves to identify an article of text selected at that moment. Other ways to indicate the current position within a text list are contemplated, such as an adjacent symbol or associated with a single text article. The type or form of list that can be retrieved can be selected from a plurality of lists as a particular list of a plurality of playlists. This is initiated by the user through the appropriate buttons (user inputs). An alphabetical list typically begins at the beginning of the alphabet (for example, the letter "A" in the English alphabet), but also the audio data player 10 may have options selected by the user to start the alphabetized text list in any letter of the alphabet. The audio data player 10 can be programmed to allow the user to start at the end of the alphabet (ie, the letter "Z" in the English language alphabet), or anywhere between the initial letter and the final letter of the alphabet . It should be noted that the same principles apply to a text presented in an alphabet different from the English alphabet, as well as in nonliterate lists that. they include lists without alphabet, like symbols or combinations of the same. Controlled navigation in accordance with the principles of the present invention operates, in a manner as follows: A single rapid or momentary activation button on a button (user input) in the desired direction less than the first period of time or duration advances an article in the list and shows or provides the same in the display 21 (that is, displays) .- The direction of progress can be in any direction, but depends on the initial place in alphabetical order within the list and the address (ie, up and down arrow 64, 66). A first exemplary duration is 0.5 seconds. In this way, when a momentary press of the navigation button is received by the audio data player 10, the list moves (advances or returns, depending on the navigation key, ie, up and down, which is activated) for an article. When the user holds the button in the desired direction for a duration greater than the first duration, but less than a second duration, the articles advance to a predetermined first speed in the text advance. The first predetermined speed of text advance, preferably, is greater than one text article at a time. In an exemplary form, the second duration is 2.0 seconds and the first predetermined duration in the text advance (or decrease in the reverse direction of displacement) is five (5) articles per second. In this way, when the button is kept pressed for a period of time between 0.5 seconds and 2.0 seconds, the text will advance or decrease at a rate of 5 articles per second. When the user holds the button in the desired direction for a duration that is greater than the second duration but less than a third duration (i.e., the audio data player 10 receives a signal for a duration that is greater than the second duration but less than the third duration and / or responds to it), the articles advance to a second predetermined speed in the text advance which is greater than the first predetermined speed in the text advance. Again, such progress is shown in the display, which offers a visual confirmation of the displacement or navigation of the text. The second predetermined speed in text advance is subject to variation. In an exemplary form and to maintain the present scheme, the third duration is 4.0 seconds and the second speed in text advance is ten (10) text articles per second. In this way, when the button is held down for a period of time between 2.0 and 4.0 seconds, the text will advance at a rate of 10 articles per second. Further, when the user holds the button in the desired direction for a duration that is greater than the third duration but less than a fourth duration, the articles will advance in accordance with the third predetermined speed in the text advance, in an exemplary fashion which is page by page, preferably, with a break between the advance pages. Again, such progress is shown in the display. In an exemplary form and to maintain the present scheme, the fourth duration is 6.0 seconds. In this way, when the button is held down for a period of time between 4.0 second and 6.0 seconds, the text advances to a third predetermined speed in the advance of text or page by page. A page is typically defined as the amount of text that will fit or be adjusted in the display 21 at a time. Finally, when the user holds the button in the desired direction for a duration exceeding the fourth duration, the text articles advance in accordance with a fourth predetermined speed in text advancement, which in an exemplary form may be start a page of each next letter of the alphabet and so on until the end of the list is reached or the button is released. In this way, when the button is held down for more than 6.0 seconds, the text will advance in accordance with a fourth speed in the text advance or page by page until the end of the text list is reached. It should be appreciated that the different predetermined durations and / or speeds in the text advance (in a first or second direction of movement, for example, a forward or backward direction of text movement) are only exemplary. further, some modes (retention durations of button activation) and / or speeds in text advance can be skipped. Also, the release of the button stops the text advance at any time. Re-activation (pressing the button again) starts the process again. The audio data player 10 thus operates, adapts and / or configures to operate in the ways described in response to user input, as described herein. In another form of the present invention, controlled navigation operates in accordance with various modes, depending on the length of time the user holds the button in the desired direction and / or the number of text entries for a particular letter of the alphabet . This form of the present invention operates as follows (or is implemented so that the electronic device operates as indicated in response to receipt of user input, as indicated). A single quick press on the key for a rejection period is accepted as a valid key press. The de-rejection period may be selected as appropriate, but is approximately 100 mx or less and preferably 50 ms. However, in some cases, the de-bounce period can reach 150 ms. The rules of the rejection apply on the arrow keys 64, 66 up and down, when these keys are designated as the navigation control keys. The detection of a single rapid key press puts the audio data player 10 in a single online advance mode. In the single online advance mode, the text advances a single line by touch. As soon as the key press is detected, the audio data player 10 responds with a single line feed in the highlighting, courses and / or text. When the key rejection time period is set to 100 mx, you must have the ability to detect a key press in 100 ms. When the key is released for 100 ms and it is pressed again, it must respond with a second key press acknowledgment 100 ms later. Therefore, a second line feed can be given 300 ms from the start of the first key press and another 500 ms, and so on. Again, the direction of advance (increase or decrease) can be in any direction, but it depends on the initial alphabetical place within the list and the particular button used (ie, the 64, 66 arrow buttons up and down) . Figure 5 illustrates in visual form a mode of the advancement of a single line or line-by-line advancement. Each column 98 a-h of Figure 5 represents the same selected list of audio data files or text entries representing audio data files. The portion 100 a-h highlighted in each respective column 98a-h, represents the display 21 or that can be displayed or displayed in the display 21 (collectively, display 21). While the audio data player 10 receives a single keystroke, the lines advance one by one or move through the display 21. In this way, each keystroke moves an upper line of text out of the display 21 and moves another line of text within the display 21. This happens for each key press. In this way, Figure 5 represents seven (7) one-line forward mode key presses. It should be appreciated that while the highlighted portion 100 moves with respect to the list 98, this is only to show the way the text moves through the highlighted area 98. When the same key is held in the desired direction for a period of time or duration, the audio data player 10 goes to a first predetermined speed in the text advance mode. At the first predetermined speed of the text advancement mode, the text advances and is displayed at a predetermined speed or by a predetermined text advancement scheme. This can be incorporated as an accelerated mode or a line-by-line mode of fast scrolling. In line-by-line fast scrolling mode, the text advances one line at a time but in a continuous and fast way. Again, this unfolds. Preferably, the fast form is as fast as the system can respond and the display 21 can respond without experiencing latency or other deployment problems. In an exemplary manner, the line-by-line fast scrolling mode is initiated when the key is held down for more than 500 ms. The audio data player 10 will continue in line-by-line fast-scroll mode until the key is released, until the end of the text list is reached or until the audio data player 10 enters a second default speed of the text advance operation or mode. The audio data player 10 is caused to enter at the second predetermined speed in the text advance mode in response to user input of a certain duration. This second predetermined speed of the text advance mode can be incorporated as a fast paging mode. With respect to the fast paging mode, the audio data player 10 enters the first paging mode based on the following conditions. When the first character of the selected list that is in line-by-line fast scrolling mode does not change for a designated period of time, then the audio data response 10 starts the fast paging mode. The designated time period can be called as fast page time. The fast paging mode is used until the first character changes or the end of the list is reached. Within the fast paging mode, there must be an adjustable page pause. The adjustable page pause in milliseconds (ms) provides a pause for each page so that the user can recognize the page / data. In an exemplary form, the fast paging time may be 3.5 seconds while the program pause may be 500 ms. With the use of these parameters, the fast paging mode will have a very smooth scrolling from line to line until a long list with the same initial character is found. Then it will enter the fast paging mode in order to advance that section more quickly. Figure 6 visually illustrates a mode of the fast paging mode. Each column 108 a-h of Figure 6 represents the same selected list of audio data files or text entries that represent the audio data files. The portion 110 a-h highlighted in each respective column 108 a-h represents the display 21 or that which is shown or can be displayed in the display 21 (collectively, display 21). While the audio data player 10 is in the fast paging mode, the text pages advance one by one or scroll through the display 21. In this way, holding down the key moves one page of text at a time in the display 21 and moves the previous text page of the display 21. In this way, Figure 6 represents seven text advance pages while in the fast paging mode. It should be appreciated that while the highlighted portion 100 moves with respect to the list 98, this is only to show the manner in which the text moves through the highlighted area 100. Once the fast paging mode has reached a character change of the initial letter of the text list, the audio data player 10 enters a predetermined third speed of the text advance mode in the operation (mode) then of continuous receipt of user input. In one form, the third speed of the text advance mode is an alphabetical shift mode. The preferred alphabetic scrolling mode is maintained until the end of the list is reached (assuming the key has not been released). In particular, each page is displayed starting with the letter of the alphabet. Figure 7 illustrates in visual form, a mode of the alphabetical paging mode. Each column 118 a-h of Figure 6 represents the same selected list of audio data files or text entries representing audio data files. The portion 120 a-h highlighted in each respective column 118 a-h represents the display 21 or which is displayed or can be displayed in the display 21 (collectively, display 21). While the audio data player 10 is in the alphabetical paging mode, the text pages advance one by one or are displayed through the display 21. In this way, holding down a key moves a page of text that starts with the next letter of the alphabet on the display 21 and moves the previous text page of the display 21. Thus, Figure 7 represents seven pages of text advance while in the alphabetical paging mode. It should be appreciated that while the highlighted portion 120 moves with respect to the list 118, this is only to show the manner in which the text moves through the highlighted area 120. Of course, as with the other modality of the present method, the release of the key starts the process again. It should be appreciated that the different modes described here can be combined with other modes or some out-of-sequence modes. For example, another form or variant of the present invention is to remain in a list mode until the first letter of the alphabet changes. At this point, a synchronizer can be started, which when it expires puts the audio data player 10 in a paging mode. Again, different ways are contemplated to offer navigation through a list and the selection of an item from the list. It should be appreciated that the implementation of the present invention in other types of electronic devices may differ from those described in connection with the audio data player 10. In the same way, the navigation principles and / or the article selection as described here (such as software and / or hardware), can be applied to other devices and / or components that use audio data files. For example, the principles described herein with respect to navigating through a text list of audio files apply to the implementation of the same on a PC such as music management software. Referring now to Figure 8, there is illustrated a flow chart, generally denoted by the number 150, which represents an exemplary method in accordance with the principles of the present invention. An exemplary method can be used in various electronic devices such as a PC, portable audio data player or other devices that provide a display and / or others as described herein. The electronic device is programmed, operated, adapted and / or configured to achieve method 150. Method 150 starts with step or block 152 where the advancement and deployment of a literate list of text articles by a text article in response at a key press of a first duration. After recognizing the pressing of the key as in button 64, the electronic device advances and displays a text article for the user to visualize it. Preferably, the display shows as many text articles as it fills the display, but will highlight only the "advanced" text. In step 154, the electronic device determines whether the key pressed by the user is released or not. When the key pressed by the user is released (ie, YES), then the electronic device waits for another key press of a first duration for step 152 and advances and displays the next text article. In this way, the only continuous activation (pulsation / non-pulsation) of the key causes a single advance or individual advancement through the alphabetized list of text articles. To continue with step 154, when the key pressed by the user in step 152 is not released (i.e., NO), then the program flow proceeds to step 156. In step 156, advancement and display of the alphabetized list of the text articles is provided at a predetermined speed of text items in response to the keystroke by the user of a second duration. In this way, as the user holds the key down (continues to press or activate the key), the alphabetized list of text articles is scrolled through the display at a predetermined speed of text articles (for example, by a page to the time). In step 158, the electronic device determines whether the key pressed by the user is released or not. When the key pressed by the user (i.e., YES) is released, then the electronic device starts the process again, waits for a key press (i.e., step 152). Another key press of a first duration for step 152 advances and displays the next text article. To continue with step 158, when the continuous keypress is not released by the user in step 154 (ie, NO), then the program flow proceeds to step 160. In step 160, the progress and display of the alphabetized list of text articles having an initial letter that is later in the alphabet relative to the initial letter to a text article displayed at that time is provided in response to a key press by the user of a third duration . Thus, as the user holds down the key (continues to press the down key or activate the key), the alphabetized list of text items scrolls through the display that begins with text items that have an initial letter that is together in the alphabet in relation to the initial letter of the text article displayed at that time. The release of the key at this point starts the process again. It should be appreciated that the flow chart 150 described above and illustrated in Figure 8 provides an exemplary mode of operation of the present invention as described herein. The present invention can be implemented with the use of fewer steps or steps than the steps described in flow chart 150. This is reflected in the claims. In addition, more or less steps may be implemented in alternative embodiments of the method, method or operation 150 of the present invention in accordance with the principles thereof. Also, subgroups of the above method 150 can implement the principles of the present invention better than the entire process. Variations are also contemplated. While this invention has been described with a preferred design, the present invention can also be modified within the spirit and scope of this invention. Therefore, this application is intended to encompass the variations, uses or adaptations of the invention with the use of its general principles. For example, whether a single key is pressed in several directions or a plurality of items, each representative of a particular address, used to implement the principles of the invention. Furthermore, the application is intended to encompass such sections of the present invention that fall within the practice known or accustomed in the art to which the invention pertains and which fall within the limits of the appended claims.
