If I understand correctly, you speak about toolbox menu,

Yes.

Quote:if so, I'm sorry but there are no more free soft menu here.

Between "App" and "Cat", there is the "User" menu (the one that lists user programs).

Thanks for your valuable feedback. The "User" menu didn't show here so far, that's why I assumed it would still be unoccupied real-estate in the soft-menu.

Quote:however, I liked that idea.

Fortunately, the fact that "Last" cannot be added to the soft-menu doesn't break the general idea.

Let's see: While Shift + "OK" might work nicely semantically as well, it wouldn't save keystrokes (compared to "0" or "EEX") or improve on the usability idea that all functions of the device should be reachable through any input method without being forced to combine different methods (some may be more convenient than others, but they may not be available all the time or may be difficult to memorize or perform by some users or in some usage scenarios). Alternatively, pressing the already selected soft menu entry (like "Math", "CAS" or "App") again is already occupied with closing the menu again, so this won't work well either.

But if we slightly change the proposed behaviour, clicking on the menu's title bar could serve as something between the proposed functions for "0" and "EEX":

Pressing the (blue) title bar of the menu (like "Math") while the menu's sub-menus are still closed, would open all sub-menus at once according to what was invoked the last time (similar to a sequence of "0"), but not execute it immediately (as "EEX" would do). At present, clicking on the title bar with the sub-menus closed does nothing, so no documentation would have to be changed. Further, if the user would click on the menu's title bar with some or all of the sub-menus opened, it would close all the sub-menus but keep the main menu open (just as it does right now already).

Greetings,

Matthias
