I actually found out you can use Shift buttons on Xpadder, and they're better! You can set 'hold shit' (while holding the button), one way shift or two way shift.
Two way means
Set1->Press button->set 2>Press again->Set
One way means
Set1->Press button->Set 2
Then you need another one way to get back ;]
Very, very fun, play around with it :P
