To deal with shotcuts you have several possibilities.
1- Some keyboard shortcuts are listed next to the items in the main menu (just open menu list and check out).
2- You can also find shortcuts listed in Microsoft Help (lookup "shortcuts" or "keyboard", then choose the "Keyboard Shortcuts" topic). The Help topics are grouped by function.

3- To print a list of all the keyboard shortcuts (about 10 pages, organized alphabetically by command name), Word has a built-in macro:
a- Choose "Macro" from the Tools menu, then choose "Macros".
b- Select "Word commands" from the list in the Macros in box.
c- From the list in the Macro name box, choose "ListCommands"
d- Click "Run".
e- In the List Commands dialog box, click "Current" menu and keyboard settings.
f- The macro will run, generating a document in table form that you can print.
N. B.: If you make any changes to shortcut key assignments, the changes would be included in the printed list of shortcut keys.
