I've tried multiple times to create a keyboard shortcut to simply display the list of keyboard shortcuts (not on the left side, but from the top -- the star icon). I've tried different keys and combinations -- none are working. What am I missing?
Alt-a will pop open the favorites menu, assuming the label is "F&avorites" if you edit the menu in Customize mode.
The character with an & before it is the Alt-? hotkey and will be underlined outside of Customize mode if you open the menu via the keyboard; it may vary with other languages, and you can change it if you like.
