I momentarily mixed up "break" and "continue".  (I may owe
Ethan a beverage of his choice or something.)  It has dawned
on me there is really no elegant way to break out of a while()
loop from within a case statement.  But anyway, that doesn't
lessen the main point that the 'N' and 'G' cases should exit the
'record()' function to avoid X11 events not being processed.
I guess "return 1" is the only way to do that.
