In the keyboard shortcuts menu, Outline is listed twice, with the second one actually corresponding to the Elements shortcut according to the Preferences Data Store.

Secondly, I have not been able to get some of the keybindings to work for me. All of the mod + option + number shortcuts were not working for switching between outline, inspector, etc. I tried changing the Elements keybinding back to the mod+shift+E that it was in Pro 5.x, but this also did not work.
Others, such as copy + paste, duplicate, and full collapse, are working as expected.
