A family of Microsoft word processing software products for creating web, email, and print documents.
Assuming that you meant to say "I don't have any shortcut to click and assign," I still don't know what you mean. Do you mean that you can't locate the macro you created? There will be no keyboard shortcut to assign until you have entered it in the box that says "Press new shortcut key."
I emphasize press rather than type because some users have misunderstood. In order to have, say, Alt+Shift+C appear in the box, you don't actually type that out but instead press the Alt, Shift, and C keys together.
