Steps to reproduce the problem:
1. I am writing a Dev tools extension to add a subpanel to Elements panel. Extension is called 'Redder' ( see the image)
2. Is there a way to reach this extension with keyboard.

Right now chrome has a short cut keys to launch Dev tools and switch between main panels but not the sub panels (https://developers.google.com/web/tools/chrome-devtools/iterate/inspect-styles/shortcuts?hl=en#accessing-devtools)

3. Also, is there a way to assign shortcut key to go to my extension panel directly (before launching Devtools)

What is the expected behavior?
keyboard access to extension.

What went wrong?
Can't navigate to the extension with keyboard only.
