For IntelliJ IDE:

How do I go back to the code that I was reading after I clicked:

Command Click for IntelliJ.

Same question for after I found usage and want to go back.

OS is macOS.

CodePudding user response：

To go Back on Windows/Linux:

Ctrl Alt Left

On MacOS:

Command [

The same is possible from the menu:

Navigate > Back

Same question for after I found usage and want to go back.

Just go back to editor from usage window:

Esc

Go back to editor and hide find window:

Shift Esc

It works for hiding other recent window too (Project, Run ...)

Also, keymap reference is available:
