Hi,

I have two possible situations that I need to differentiate between, and I'm not sure how to do it - The first situation is the user deletes selected text by overwriting it with a new character.  The second is the user deletes selected text by pressing backspace/delete, and then enters a new character.  I thought this would be fairly easy, but I've been trying to figure it out for awhile and haven't gotten anywhere. Does anyone have any ideas for how I could accomplish this?

Thanks,
Alex
