Assigning keyboard shortcuts to user scripts in Xcode 3

You used to be able to do this prior to Xcode 3, but I can’t see how to do this in the current release. Anyone know how? Without this feature the scripts menu becomes next to useless (for my usage patterns).

Update

Roberto Cruz was phenomenally quick and contacted me only 10 minutes after I wrote the above post; you can assign shortcuts directly in the "Edit User Scripts…" window by double-clicking in the right-hand column in the script listing. Believe it or not I had actually looked for such a feature and failed to see it…
