Hi Karl,

ouch, so my plan is completely wrong... it was roughly this: 1) learn
how to create synthetic keyboard events, 2) learn how to send these
events to morphs with the debugger turned on, 3) use that to find the
actions associated to typing certain keys in certain places, 4) become
less of a beginner...

I installed your two .mczs and tried this,

  EventRecordingSpace open

and I got this error after just a few keys and mouse clicks:

  MouseButtonEvent(Object)>>doesNotUnderstand: #eventType

I also took a look at the snapshot/source.st in the .mcz with Emacs
(!!!). I search for "keyboardevent" there case-insensitively, and
found very few occurrences - and none of them very enlightening...
"keystroke" has lots of occurences, but same.

Can I ask you for some suggestions and hints?

  a) How do you do my (3) above, i.e., "use that to find the actions
     associated to typing certain keys in certain places"?

  b) I've tried to learn Etoys, but many links are broken, many
     packages too, the mailing lists and forums look dead, and the
     tutorials that I could access feel very incomplete to me... for
     example, the link [1] below only has the videos 1, 10, 20, and
     30, [2] has lots of steps that took me many hours to decypher,
     and [3] shows ways to script and connect etoys that I don't have
     any idea how to do myself... when you convince people to learn
     Etoys what are the resources - including forums and mailing lists
     - that you recommend?

Thanks in advance...
