I don't understand how to use double-click-fuzz in TTY frames. You said
that TTY frames can't discern screen position differences of less than a
character, so then why are the units 1/8th of a character?
Is there a way to get the mouse coordinate position in 1/8ths of a
character to use double-click-fuzz?
