If you happen to be in context mode and you have the project column active, you can just type in the project column to refile the action to a different project.

The same thing doesn't work in project mode, though. It may be somewhat easier to open up the inspector, which can change the project. I wonder how difficult it would be to write a "move to quick entry" script that would make it a little bit easier to use quick matching on the project names.
