Copy Popup Menu to Another Computer

I love the popup menu… the icon menu that appears under a middle mouse click. I’ve built it up with all my favorite commands. However, I’ve lost it a few times and had to rebuild it.
How can I back it up, and how can I move it onto another computer?

Are there save and load options somewhere?

Thanks in advance for help!

open Document properties then go to toolbars ,then click on file at the top >> export groups>> select the pop-up toolbar ( that you customized before) then save it

now you have your customized pop-up menu , in any computer just go to Document properties >> toolbars >> file >> open , and you have it

(( after finish don’t forget to go to Document properties>> Mouse >> in middle mouse button >>popup this toolbar : and select your new customized toolbar’s name .
