I continually have to look these up, so I'm holding the link here on this site.
I find the help button in Docs does not have all the shortcuts I'm looking for, most notably the "insert comment" shortcut key which is "command+option+m". Less clicking when I get my students using Docs for their writing. :)
This will become important if I ever get my next task off the ground: daily warm ups using Google Docs which should get some form of feedback (i.e. comments) from me (perhaps on a weekly basis. . .).

Sorry, no pics for this one.
