Simplest way to capture "keystroke representation" to clipboard
I wrote a tiny program for you. It'll type out any key combination you type, so after you start it, switch to Word with your mouse. You can exit it at any time with the escape key. I can share the source code if you want, there's not much of it: keystroke_grabber

If you want to make it easy to start, you'll have to drag it into the bottom right of the Dock where the trash can is, because it's not "Appy" enough to earn a space with the big boys (other apps).
