>What I'd like is a way to avoid adding a record if the down arrow is pressed accidentally and prevent the user from going 'Oops!'. I can think of adding a "Delete record" button, but isn't there a more 'elegant' way?

Oh, I see. Use buffered tables, then, to remove the just added record, you can do a TableRevert(). Look in the Articles Section for John Koziol's article on Table Buffering for all the info you'll need.
