IF, y'all know this, well, that's just ducky Just pretend you never saw/read this. For the rest of you, here it is...

For windows that include Ribbon:

Example... the View tab is hit & the View Ribbon shows/opens... if, that same tab is hit, again, its Ribbon will close/no longer be showing. Holds true for all Ribbon tabs.

OR

You can have, only, the parts of the Ribbon showing that you want or need & only, whilst, you want or need (1 of) them.

Cheers,
