I’m finding that Cmd-period is attached to “Complete” even though the Preferences don’t have any shortcut for that command.
I checked whether that was a shortcut I had set in System Preferences but did not find anything.
I’m worried that there is a conflict between Cmd-period that tries to simultaneously stop a script and complete at prompt…
For the longest time, escape was the shortcut for completion, along with F5. Then Apple removed it, and a lot of people weren’t happy. Xcode brought it back, and after a time so did Script Debugger. But unfortunately escape and command-. are twinned, so the latter triggers completion when a script’s contents has focus. But we should see if there’s a way to separate them.
