How to add shortcut for Insert Equation in PowerPoint 2016? PowerPoint 2016 for Mac finally includes the new-style equation editor (which was already available in Word for Mac and PowerPoint for Windows).  An equation can be inserted using a ribbon button (Insert → Insert Equation).

How can I add a keyboard shortcut for this?  Is there already a keyboard shortcut for it?

For Word I could use the OS settings from System Preferences → Keyboard and set up a shortcut for the menu item named "Equation".  But I cannot find a corresponding menu item in PowerPoint.  I can only find this feature on the ribbon, but not the in menu.  Is there any way to set up a keyboard shortcut for it?



Update:

Since the situation seems to be in flux, here's an update:


Older versions, including the one that was current when I asked the question, have the undocumented shortcut ⌘-⌥-=. There is no menu item in this versions that would allow setting up a shortcut manually. Answer by theoden.
More recent versions do not have a shortcut built in, but they do have the menu item Insert → Equation, which makes it possible to set up a shortcut manually. Answer by suntoch.
The shortcut posted by theoden seems to be broken in new versions.
As a workaround one can just go to the System Preferences => Keyboard => Shortcuts => App Shortcuts and add another one for Microsoft PowerPoint with the "Equation" as Menu Title.
