Thanks, Ken.  I had thought of that but wrongly imagined it would be as obfuscational 
as a jump table.  Now that you've suggested it, I realize it could be done in-line 
without having to reorganize any legacy code:

	::' some code that doesn't update the master:
	::pushkey "A"; end:
	@KEYA::' continue with code that does update the master:
	::goto exit  ' finish up and return to @entsel:
	::':
	::' some other code that doesn't update the master
	::pushkey "B"; end:
	@KEYB::' continue with the other code now in update mode:
	::goto exit:
