CODE: SELECT ALL
rightx Left - right arrows
righty Up - down arrows

leftx A - D
lefty W - S

key('1') 0-9
key('a') A-Z keys
key('enter') All the Windows function keys. (lctrl, rctrl, space, backspace, etc...)
key('numpad1') 0-9 Right numpad keys
key('+') Numpad operations (+, -, *, /)

key('lbutton') Mouse keys (mbutton, rbutton, xbutton1, xbutton2)

get_var('variable') ... for script.

What do I do with this?
