Devote a touchpad entirely to one app - and use one finger swipe as gesture.

Hi.

I use a regular mouse but have a touchpad lying around not doing much.

I'd like to use it exclusively in one program (Reason - Digital Audio Workstation) and use it entirely for navigation. In Reason, navigation is performed via mouse but with a modifier key.

Is there any way to make it so that in Reason I don't have to use the modifier key with the trackpad (i.e. all trackpad movement responds as if CMD was being pressed at the time?
