- Atari Works is just unsafe in general. A program should always provide
- a way out if a user accidentally lost important data. A single-stage undo
- is simply not enough to avoid irritation. Once a solution has been found
- for that (e.g. the trash can in Edith) control + A is no longer a problem.
- It is also highly standard on other platforms (like ^W for close windows).

-
- Hit UNDO once. Should work, shouldn't it? I like shift-backspace but find
- shift-delete a bit strange. Ortogonally thinking, it should mean:
- delete everything right to the cursor. But it means delete line and line feed
- altogether!

- I agree in part (basically things like shift-delete).

- There is one good argument for Atari's codes ^W and ^A. If anyone should
- ever be thinking of buying an Atari and s/he is familiar with a Macintosh
- or good X-Windows applications, then the Atari guidelines will make programs
- look very familiar. ^U for close window and ^W for wechseln (cycle) will
- feel very strange to him/her.

- Shortcuts are much less regularly used than letters for typing text.
- The biggest problem for shortcuts is remembering them. Therefore, they
- should, as far as possible, suggest their use, like ^A for All, ^Q for
- Quit, ^W for close window. One exceptions is perhaps cut/copy/paste
- (^X ^C ^V) which is ergonomical, and by now known by more than half of all
- computer users in the world (?)
