Microsoft Word does not respond to keyboard shortcuts I have a MacBook Pro with Microsoft Word 2011 installed on it.

For some reason, all the editing keyboard shortcuts - such as Cut: Cmd + X, Copy: Cmd + C, and Undo: Cmd + Z - does not work in it.

My friend who also has Microsoft Word 2011 on a MacBook Pro has his keyboard shortcuts working fine.

This situation really hinders my work, what could be the problem?
Check in the edit menu and see what MS Word thinks its shortcut keys are for cut, copy, and paste. 

If they're not the keys you’re expecting, maybe something was accidentally configured in Word’s preferences, e.g. some alternate key mapping.  

Also, verify that there are not alternative key mappings specified in the Mac System Preferences, both system wide and application specific, that may be modifying your shortcut mappings to other keys.
