	  Several key sequences enable the user's to access certain
	functionality directly, bypassing the menu procedure. The 
	key bindings are shown on the right side of the buttons in 
	the menu bar. Some brief examples of these functions are:

	"Control<key>p" - begin processing immediately
	"Control<key>a" - bring up the menu for setting a delayed
			  processing time
	"Control<key>s" - pause/resume processing in progress 
	"Alt<key>q"     - exit the program
