> Definitely a weird bug in keyboard handling, some kind of confusion between numbers and letters, I will look to fix it tonight.

If the number of keyboard shortcuts increases, please do not loose of sight the fact that there are many users with non-american keyboards. Even the French/French keyboard of Frenchy Pilou is probably different from my French/Belgian keyboard ! ;-)
I know this can cause some issues when assigning hotkeys although I don't know exactly how this can be avoided...
