What is the keyboard shortcut to insert a comment during track changes in Word?

When I am editing a Word document using track changes it would be nice not to have to got to the mouse to insert a comment at the cursor (since this is most of what my editing consists of).

What is the keyboard shortcut to insert a comment at the cursor in MS Word on a Mac when using track changes?

I am running Word 14.2.5 and OS X 10.5.8

Solution 1:

Insert a comment
⌘+OPTION+A

Turn track changes on or off
⌘+SHIFT+E

From here

Solution 2:
