How to activate "starred", "explorer" or "backlinks" pane by keyboard?

I have dragged backlinks tab to from right left sidebar to Utilize wasted screen space along right edge on small screen, because I mostly do not need to see search and backlinks at the same time.

When I have search tab in left sidebar displayed, how do I switch to “starred” or “backlinks” tab by keyboard without having to mouse click on corresponding tab?

I can have them displayed half height of screen each but that limits view of each on small screen.

If there is a reliable sequence of “blind” keystrokes, we could simulate them by one hotkey in AutoHotkey (or Keyboard Maestro).
