Can be assigned to operation buttons.

The same operation and effect can be obtained by the operation flow shown in FIG. In the figure, first, the CPU 110 of the e-mail system reads the display / non-display data of each bar from the bar display management data and displays the read data according to the set contents (step 661). Next, it is determined whether the attribute display button 910a has been pressed and a display instruction has been issued, or whether or not the display instruction has been issued (step 662).
If the display command is issued by pressing the attribute display button 910 (YES), it is determined whether the display / non-display setting of the bar display management data of the destination bar 930, the attribute bar 940, and the attached bar 950 is non-display. (Step 663) If non-display is set by the setting contents of each bar (YES), the corresponding bar is displayed (Step 664),
If the display is set (YES), step 6
The display contents of 61 are maintained. If no display command has been issued in step 662 (NO), the display state of the bar display is determined, that is, the set contents of the bar are determined (step 665). The state of 661 is maintained, and if non-display is set, the corresponding bar is set to non-display (step 666).

Further, in the embodiment shown in FIG. 4, in step 630, display / non-display is determined for each record recorded in the bar display management data. For example, the destination bar 930 and the attribute bar 940 And the display / non-display records of the attachment bar 950 are grouped and determined. If at least one of the three data is displayed and recorded (set), the attribute display button 910a causes the attribute display button 910a. One bar may be displayed / hidden at the same time. By doing so, the bars required for transmission can be displayed and hidden at the same time, so the large area is fully utilized when creating the main sentence, and the bars that need to be confirmed at the time of transmission are collectively Display, it is possible to reduce forgetting of the confirmation contents. In particular, this is effective when the user wants to refer to the received mail display screen for a moment such as “attached file” or “destination”.
