In the console, enter "sublime.log_commands(True)". When you hit super+p, it will display the running command. You can also utilize FindKeyConflicts
to find specifically what plugin any interference is coming from. The former solution will display the command, but not the plugin (though you could probably figure it out anyways). You may also want to try "sublime.log_input(True)" to ensure the correct key strokes are reaching the editor.
