Is there any shortcut to insert a math equation for Powerpoint 2016 Mac?

Question

I'm looking for a shortcut to insert a math equation for Powerpoint 2016 Mac version.

I had been using PowerPoint 2010 windows, which I could "insert a math equation" using the customized ribbon. For example, I could insert a math equation by "Alt+4" if I set "insert equation" function as 4th element in the customized buttons. Please see attached pictures. This is super convenient!

It seems that this customized ribbon function is not implemented in Powerpoint 2016 Mac so that I cannot create a shortcut in the same manner.

Answer 1

I use Fn+F1 and it worked :) Good luck!
