Yeah I'm not so sure about messing with enter for that, since it is already being used at that point as an alias for pushing the "Done" button...

I think maybe a good way to do it would be to have some option like "Apply distance constraint immediately" under Options > Snaps that when checked would then make it behave like you were talking about.

It should not be difficult to add this in for v3 - I've added it into the wiki wishlist to help keep track of it.
