>>> TeXworks does not provide keyboard shortcuts for the menu bar, which are normally accessed with the ALT key (Alt-F = File menu, etc.). Perhaps this is not considered necessary since many commands have their own shortcuts (Ctrl-S = save, etc.)--but not all of them do. Unless we want to give every command its own shortcut (probably not realistic or easy to remember), let's add the usual shortcuts to the main menu bar and the items on each menu (with an underlined letter). I think many TeX users are good keyboardists who would make use of the additional shortcuts.

On the mac, the programming interface offered virtual support for such keyboard shortcuts as an inheritance from the NEXT days (OS X is based on Next computers).
But IIRC this was not fully implemented in the user interface.
On Mac OS X, to access a menu item without the mouse, you
1 - Move the focus to the main menu bar
2 - navigate through the menus using the arrow keys
3 - use the space key to simulate a mouse down
Instead of navigating with the arrow key, you can type the name of the menu or menu item,
in most of the cases, the first letters suffice. It is somehow less comfortable than assigning a shortcut to each menu item like windows does
but it works as is with all the apps, including TeXworks of course.
The problem is that the keystroke is also captured by the text window :
1 - open TeXworks
2 - press keys: Ctrl-F2 "F" "I" <space> "S" <space>
This activates the Save command from the File menu.
You see the problem in the untitled document where keys "F" "I" <space> where captured such that it starts now with "fi ".
This is an unexpected result solved by simply "undoing".
I consider this a low level bug and I would not be surprised if it were a problem in Qt itself.
This on TeXworks r511, OS X 10.6.2
