Hi I'm John (mach3 newbie)

With my other cnc router and control software, If I want to jog 12" from any point, I can enter 12 in a X/Y box and click the arrows and jog around the table 12" at a time.  When manually zeroing I can set the step size as needed to move in small increments.

Is there a way to do that in Mach3 short of entering GCode commands?
