Jump to editor shortcut in Intellij IDEA

Question

I can use F12 to jump to project tree (if it was the last tool that I used), but is there a shortcut for jumping back to editor?

Answer 1

The most elegant way found in mac: ctrl + tab + p

ctrl + tab: open recent file, always last file opened
ctrl + p: last line in mac default keymap

Answer 2

Pressing F4 (Jump to Source action) in a selected resource in the Project View opens the editor with focus.
