Hi Chris, just to let you know, I'm getting a set of accented characters in the editor when I try to type numbers and operators on my keypad (English on Windows 7) and also the ¬ character. Actually, the numbers type numbers, but jump rows or columns first, like they've inserted control codes! The top row above QWERTY are fine of course, but it might be useful for number-heavy stuff to have the keypad.
Cheers,
