I tried using InKey, but there are two problems.  First, InKey not only
tells me what the last character was, it also removes the event from the
queue.  That means if it isn't a character I want to do something with,
I must either do something with it anyway or throw it away.  Now, I could
write an XCMD to put it back on the queue, or I could write a replacement
for InKey that would leave the character on the queue, but I would still have
the second problem: the Idle handler doesn't get called often enough to
guarantee that I catch all the characters, and in fact it's easy to type
fast enough that this is a problem.

I think HyperCard itself should have a system message called On Keystroke.
Are you listening, Dan?
