I know this is a dumb question, but... How do I carriage return in the FIND and REPLACE fields?

Update.. Found it. It's ctrl+RETURN, which seems a bit daft to me. All in all, this is a lot less friendly than TextMate, as are a lot of other aspects of ST. But then, I guess only jerks want their text editors to be user friendly. Real programmers love the struggle, right?
