Re: Chording keyboard

(Sending to me as well as the list's unnecessary, btw, I just end up
with two identical copies <G>)

  That would be implementable in the Keydler, though I hadn't thought
about simple state machines, they're already there in effect (for
example: Caps Lock is a very simple 2-state state machine!)  The Keydler
will have 512k of chord mapping space, so such should not hit a space
limitation at all!  Just need to write code to do it all...

  For myself I think I'd want different chords, or a Shift button; to
each their own <G>  That's what mapable programmable chords are all
about <G>

  I've mumbled about "Mash All Keys" == "Send Ctrl-Alt-Del to host" on
the Keydler, have yet to write that code but it'd be do-able (Hard to
accidentally - or intentionally - mash all 18 keys one-handed...)

  Think about what to do with 3, 4, or 5 space bar hits in a row.  Need
ability to avoid Sentences That All Look Like This, but also ability to
do that (when desired or needed) intentionally!

  Mark,
