a couple hurdles I had with Rev

[Jared Smith]

Here are a few things that I've been confused about:

1) How do I find the number of times a certain character appears in a
string? The "offset" function only finds the first occurance, it
doesn't count them.

2) Why isn't there a deleteKey handler? There's a backspaceKey and a
few others, but I'd like a way to respond when the user presses the
delete key.

Thanks and my complements to the guys at RunRev - really excellent
software so far.
