If you are using a recent version of Word, Click Help, View Word Help, type "keyboard" in the box, select the "keyboard shortcut" item that should come up. When you click Search, the default item that comes up should give you about 11 pages of shortcuts. (click the "Show All" button to avoid lots of clicking.

You can print the "help item" for reference.

Word is the primary program in Office, and settings/features there largely control what happens in ALL WINDOWS COMPATIBLE PROGRAM.

Older Word versions do have similar summaries in Help, but they are a little more difficult to find.
