Jump to editor shortcut in Intellij IDEA

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?

Esc usually brings the focus back to the editor.

With Alt + Home you can actually put focus on selecting the file and hit enter in order to go to the editor.

Esc is not always going to put the focus on editor.

For those on Mac (you don't have a Home key), use Command + E to open the recent files then hit enter.

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

Another easy way to get from Terminal to Editor (on Mac) with two keys that are close together: Press ⌘1 to go to the project tool window, then hit Esc.

You can use ctrl + tab Navigate between files opened in the editor, and tool windows.
