How to detect an image or graphic deletion?

[Doug Lerner]

When I move an image or graphic, the moveControl message is sent. Similarly,
when resizing, the resizeControl message is sent.

But when I delete an image or graphic it looks like just rawKeyDown and
backSpaceKey messages are sent.

Isn't there something like a deleteControl message?

Do I just need to write a backSpaceKey handler and check and see if the
target or the selected or whatever was an image or graphic?
