Hi,
I think i have seen this done, by using the ASCII vale for the Key and
the worksheet update event, but i honestly can't remeber.

However, i would strongly suggest not to use this method, and go for a
button instead.

No matter how bad you user are, an button, with save a close on it is
very easy to use, also, i'm quite good on PC, and i press entre by
mistake all the time!

Anyway sorry can be of more help

Good Luck
Ross.
