Comment 2 for bug 343219

" A user may just prefer using the menu. Maybe he has mobiliy problems and prefers to use Alt F1 to open the main menu than to tab over to FUSA. "

A major problem here is that it is virtually impossible to reach FUSA from the keyboard. The Gnome-documentation claims that you switch between panels using Ctrl-Alt-Tab, which doesn't actually work, at least with desktop effects enabled - it just switches between open windows instead. This leaves keyboard-users unable to log out, if they have FUSA enabled.

(The panel situation needs to be resolved in a better way, too, but I guess that's for another bug)
