Well currently I dont have a shortcut for the shading pie as its overlay is directly in the viewport( Logically could see this somewhere on z or alike and “Zoom to border” which is located there isnt the most neccessary function aswell.) What did you have in mind as shortcut?
I have shortcuts for the shortest path fill and the add menu though.
What would be your shortcut idea for these? I have them on Shift+Ctrl+Alt+LEFTMOUSE which isnt the nicest one, but to me it makes sense there as Shift+Ctrl is the Shortest Path and it does align with the basic selection logic that way.
For the different add menus I have those on Ctrl+Tab as the operator search menu and quick favorites are also located there ( works fine under windows, not sure about others)
I will answer on your other reply later when I have more time.
