Add tooltip to Excel Add-in Custom Ribbon UI XML

Question

I am creating an Excel Add-In that has a custom Ribbon UI. I would like to add a tooltip for my buttons. What XML attributes can I use to set this?

Answer 1

You can use "screentip" and "supertip":

<button id="insertStuff" screentip="Tooltip title" supertip="Long description" ...

BTW, you should have autocomplete normally when you edit the ribbon XML in VS. If you don't make sure you have Ribbon schema file available.
