Pycharm: How to focus on Editor when hit a debug point

I am using a mac, with Pycharm version 2018.2.4 Community version.

When I run a debugging session using the debugger and hit a debug point, I have to click on my editor using my mouse to be able to type code on the editor. If I don't do this and hit my keyboard directly, Mac will complain with some "bing" sound, signaling the keyboard input is not valid to any application (my opinion).

How to make my Pycharm auto focus on the editor when hitting the debug point? Or at least focus on the debugger so that I can hit ESC to focus on the editor?

I have selected "Focus application on breakpoint" in the setting.
