Focus Panel with Keyboard?

Is it possible to set up Premiere Pro to be able to switch to a target Panel or Extension? There are two interactions we have in mind for this:

1. [Registerable?] Keyboard Command to open or focus a panel/extension.
2. OS keyboard commands to switch to floating window.

It's really annoying to keep having to use the mouse to switch to a specific extension panel.

What's more, with respect to #2 (on macOS, at least), it seems that it's possible to use the built-in window-switching keyboard shortcut [⌘`] (command tick) to switch from a floating panel to the main application, but not back to the floating panel! Once the main app has context, it appears to swallow the command entirely...
