Thank you very much for your feedback!

I can't do it for the standard QAT either. I tried with Application.CommandBars.ExecuteMso ("???") but i don't have the idMso for the QAT. The idMso "MinimizeRibbon" hides/displays all the tabs but not the QAT

With a custom QAT put in startup folder, I have a problem with startFromScratch="true" which hides all other standard tabs (except the custom ribbon)

Is there a solution?

Sincerely,
David
