Looking to make custom Ribbon buttons

[akatsuki]

Any really for idiots guide to making custom Ribbon buttons?

I'd like one that toggles between "Center Across Selection" on and off.

Another that toggles through Plain, Underline, Single Accounting Underline to ideally replace the underline button.

Is this possible? I downloaded the Spreadsheet Guru's CAS button, and it works, but replaces the entire grouping there.

Hi Akatsuki,
this is the guide I've been using for quite some time, no clue if there is something easier: https://www.rondebruin.nl/win/s2/win001.htm

You can add any existing buttons or commands to a custom Ribbon or any Macros to a Ribbon as Buttons.
You can also set what is the primary Ribbon by changing the order the ribbons appear.
You are even able to replace all the ribbons, except the context ribbons, with your own custom versions.

Your question, to me, is more about two macros that cause your desired actions.

Don't forget the option of using the Quick Access Toolbar or QAT

For your specific requirement (a Center Across toggle), please see How To Add A Center Across Selection Button To Excel's Home Ribbon Tab. Excel MVP Chris Newman has written a small add-in that adds the button to the ribbon for you, and I use it on all of my computers.

Bravo for rejecting Merge and Center, by the way.
