I have recently come across from AutoCAD as the Mac version was horrid, however I digress. 

Loving DraftSight, fantastic program, the ONLY thing I am missing is the spacebar pan command like in AutoCAD. I have had a look at Aliases in DS but can not figure out a way I can set my spacebar to Pan while holding it and release Panning tool when released.

Is this possible in DS, if so how do i do this?
