Running scripts with different key combos for different behaviour

You can use a key mask.

from AppKit import NSCommandKeyMask
cmdPressed = bool(NSEvent.modifierFlags() & NSCommandKeyMask)
if cmdPressed:
	print "Gotcha. You are holding down your CMD key!"

Key masks include:

NSAlphaShiftKeyMask
NSAlternateKeyMask
NSCommandKeyMask
NSControlKeyMask
NSFunctionKeyMask
NSHelpKeyMask
NSNumericPadKeyMask
NSShiftKeyMask

EDIT: More info on https://developer.apple.com/reference/appkit/nseventmodifierflags where I just read that this is going to be deprecated. But the sample above still works.
