I used this technique in SC once and it was quite fast (it is surprising how
much you can get done between keystrokes) - it let me capture and do
processing on a field "live" behind the scenes. In rev you could use the
send command if you don't like using idle.

on idle
put field myField into field "debug"
end idle

This might not be quite what you are after, but could could
compare captured strings at each tick or whatever period you want to find
what has changed...

Another approach might be to check for spacebar presses, so you could get
the last word entered during 'normal' typing, and go after mouseClicks and
other signs of editing as special cases only as they occur.
