like this
I add several space between the name and key, \t doesn't ajust here.
I don't think there is a better way currently, since \t doesn't work for Favorite labels.
(Unless you want to build the menu items manually, instead of using the Favorites system to do it. Then you can, but it's a bit more work to maintain the menu. To do that you can drag folders into a menu to create buttons that go to them, and \t will work with their labels.)
In the automatically generated favorites menu, the hotkeys are shown in the tooltip for each folder, FWIW.
