'Google Docs "add a comment" shortcut (⌘+⌥+M) not working [closed]

I cannot add a comment using Google Docs' defined shortcut on my MacBook Pro (Sierra 10.12.4, but I've been having this issue since Mavericks).

Google Docs Comment Shortcut

(Side note: The keystroke for entering a footnote works perfectly fine).

I've gone through my keyboard shortcut settings and assigned away all shortcuts that use the "M" key, here:

Keyboard Shortcuts Screen

(I've checked "Accessibility" and the other categories to ensure no use of the "M" key in any shortcuts -- active or inactive.)

Am I potentially misunderstanding in that the "option" key as defined by Google is something other than the Mac ⌥ key?



Solution 1:[1]

The shortcut calls for Alt. So you have to press down Fn on the Mac.

So Fn+Option+Cmd+M works.

Solution 2:[2]

The closest I got was by going through the Insert menu:

  1. Ctrl + Option + i
  2. m

None of the other suggestions worked on my iMac Pro.
