Run a macro by clicking a button (Excel 2007)

No. That's not what I want. I want to create a custom button and put it on a toolbar, maybe a new, custom toolbar. And I want my macro to run when I click the button.

I don't want to click a button to get a list of macros so I can read thru the list to find the macro I need. That's fucking stupid. I'm not stupid.

Or maybe I am. It doesn't matter. In the old Excel you could make a custom button and use it to run a particular piece of code. You can't do that any more in the newer Excel?

I've not found a way.
