Current behavior

Even though my preference is "Cmd + M" as a hotkey for toggling editor mode, the editor mode gets toggled even if I just press M.

Expected behavior

Editor mode is only toggled if I press Cmd and M at the same time.

Steps to reproduce

1. Set "Cmd + M" as hotkey for toggling editor mode
2. Write something with the letter M

Environment

• Version : 0.11.6
• OS Version and name : MacOS X, 10.13.1

PS: Thanks a lot for this nice software! My workaround currently is to just delete the toggle hotkey command in preferences.
