After a few fruitless attempts to find what I figured had to be present, I finally ran across this pretty good list here:
http://android-tips.com/use-keyboard-shortcuts-to-switch-between-applications. Some of the keystrokes may not apply due to the buttons support on the Moment. Appears to be written for a different phone, I believe that "Alt" can be replaced with "fn". My comments are in parenthesis for some items.

Other Google apps: (I couldn't get this to work on a few apps I tried)
If you are in the mood for more shortcuts on any google apps like mail, calendar, docs, try typing: “?” in the webbrowser when using that app.
You would need to enable this option in settings for mail. The other apps have this enabled by default.
(However, in at least some of the Google apps, if you
long-press the Menu button, it will toggle the text for the shortcut keys for the Menu commands in the soft-buttons.)
