Hi There appears to be a variety of ways of referring to the numerical keypad keys in the Blender Manual. I've seen: numpad3, NUMPAD_3, Numpad3, KEYPAD_3, Keypad_3, PAD3 etc. Can I suggest you pick one format, which we can then use as a standard throughout the documentation? Without wishing to start a flame war, I quite like 'Numpad3' :) Cheers. Eric
