Abstract

PURPOSE:To entirely invalidate a series of operation by one touch and to lighten the burden of a user largely by storing the content of correction by the same editing key until other editing key or cursor key is inputted, and invalidating all corrections made by the same editing key. CONSTITUTION:For instance, when a deleting key is inputted, the content of an operation storing section 3 is cleared to deal with the later depression of a canceling key, and a correction flag is set to 1 to indicate that correction was made. Here, character string in an extent instructed by the cursor is stored in an operation storing section 4. Then, the character string in an extent instructed by the cursor is deleted and the result is displayed. When the deleting key is depressed in succession, the process is repeated, and becomes the state of waiting for deletion inputting. When a canceling key is inputted, all the content of the deleting key is read out, the operation storing section 4 is cleared, and the correction flag is made to 0. Thus, operations made successively by a user can be canceled by one canceling operation.

Description

[Detailed description of the invention] [Technical field of invention] This invention relates to improvements in systems.

[Technical background of the invention and its problems]

When editing text, mistakes in editing instructions often occur. In such a case, there is an edit cancel function that cancels the contents of the edit instruction.

Many of these editing undo functions
For example, if you press the delete key 10 times to delete 10 characters and then instruct to cancel the editing, only the last character will be deleted. becomes invalid. The remaining nine characters must be entered again, which is time consuming and likely to result in another error during entry.

Therefore, if you instruct the edit cancellation operation 10 times, for example,
There is also an improved text editing system that can reproduce the 10 characters that were deleted. However, such a text editing system must memorize all operating processes, requiring a large-capacity storage unit, and especially if it is not implemented on a high-speed computer, it may cause discomfort to the user. It will be difficult to respond within the range (2 seconds or less).

[Object of the Invention] An object of the present invention is to provide a text editing system in which editing operations by an operator are simple.

Another object of the present invention is to provide a text editing system that allows editing to be canceled with fewer operations.

[Summary of the invention]

This invention stores corrections made by the same edit key until input by another edit key or cursor key, and when an edit cancel key is pressed, all corrections made by the same edit key are invalidated. It is a text editing system.

〔Effect of the invention〕

According to this invention, the user can disable all of the series of operations with one touch, so the burden on the user can be greatly reduced.

Therefore, editing operations can be significantly simplified, and appropriate sentences can be easily obtained.

[Embodiments of the invention]

FIG. 1 is an overall block diagram of a text editing system as an embodiment of the present invention. This system includes an input unit 1 consisting of a keyboard, a memory 82 that stores input text, an operation storage unit 3 that stores the same correction content input through input s1, an editing control unit 4 that controls the entire system, It is composed of a display control unit that controls the display of text, a display unit, and a printing unit that formats the text and outputs it as a hard copy.

FIG. 2 is a diagram showing an example of the key layout of the input unit 1.

The input unit 1 includes the following various keys in addition to character keys for inputting English text.

Edit keys: 101 to 117 Cursor keys: 130 Other keys FIG. 3 is a flowchart showing the flow of processing of the editing control section 4 in one embodiment of the present invention.

The editing control unit is in a main input waiting state (step S) until the user inputs an instruction from the keyboard.
O) and is waiting for a key input.

Then, the editing process according to type 1ii (==) of the input key is performed. For example, when the delete key is input, the contents of the operation storage section are first Clear step 511), and set a modification flag to 1 to indicate that there has been a modification (step 512). Here, the character string in the range indicated by the cursor is stored in the operation storage section (step 513). Next, a deletion process is performed, that is, the character string in the range indicated by the cursor is deleted (step S14), and the result is displayed (815).

At this point, the state waits for deletion input (step 816), and
Wait for instructions from the user. Subsequently, when the delete key is pressed, the processing from step 13 onwards is repeated. At this time, the storage operation section stores the contents of the delete key twice. (Also, character keys, curse steps 821 to 826,
Processes 831 to 833 and 851 to 854 are performed in the same manner. ) It is assumed that the process is again in a state of waiting for deletion input, and that the cancel key is input here. The process moves to step S41. Here, since the correction flag is 1, the contents of the two delete key presses are read from the operation storage section (step S42).
, the state before the delete key was pressed twice is restored and displayed (step 543). Thereafter, the operation storage unit is clearly set to steps S, U>, and the correction flag is set to O (step 545).

As described above, according to the present invention, it is possible to cancel operations that the user has performed successively by performing - times of undo operations. The effect is great because it can be repaired.

In the above embodiments, a baseboard is used as the input device, but it is possible to modify the input device by using a mask or a tab i-knot, or to apply it to an editing section of a machine translation system.

All such modifications and applications are included in the present invention.
