Is it possible to create a shortcut for a command that's not in "all commands"?

[PointyHead]

Word 2013, Windows 10

I previously created a keyboard shortcut for "paste unformatted" that required a single step (Alt P in my case). The shortcut was lost when I updated Windows.

When I tried to recreate the shortcut, I found that "paste unformatted" isn't listed among the "all commands."

QUESTION: Is it possible to create a new command that doesn't appear on the "all commands" list?

I'm aware of the numerous other ways to paste unformatted. I don't want to use any of them. I want to restore my previous Alt P. Sadly, I can't remember how I created this before. By the way, Alt P still works fine in my Word 2003, but not in Word 2013.



Thanks for your help!
