Let's say I edit a file and then I want to do a search (ctrl+shift+f). Then, I decided to go back to the editor.
My question is: how to do that without a mouse?

There are options which don't work:
`esc` - no, does'n work, `ctrl+k+q` - this is for navigation to the last editing position, `ctrl+tab` - no, `alt+left/right` - no.

Perhaps, I'm missing something. Thank you in advance for you help!
