Control/CMD-M shortcut is annoying Rated 3 out of 5 stars

I think the newly added ctrl/cmd-m shortcut to launch the sidebar is extremely annoying considering I am a mac user that uses this command to minimize my browser window. Anyone know how to revert back to the older version or override this key command?

This review is for a previous version of the add-on (2.9.13.1-signed).
