how to move cursor from project view to editor in Intellij Idea?

Question

I want to use only keyboard working with Intellij.

I can easyly open Project view with short cut:

Alt + 1

How to move again to editor and leave Project view open?

Without using mouse, of course.
Any suggestions?

Answer 1

Escape always brings you back to the editor.

If your Project view is closed, you need to pin it. Click on the little gear wheel and make sure, Pinned Mode is checked.

Answer 2

Escape brings input focus back to the Editor window. And Escape Escape brings the focus back and closes the popped up tool window.
