[Feature request] Keyboard shortcut to open the app

[adufr]

📝 Provide a description of the new feature

As a keyboard poweruser, I would like to be able to open/close the app with a keyboard shortcut (preferably customizable, can be disabled by default) to avoid using my trackpad/mouse.

➕ Additional Information

I didn't try it for now, but I think this is possible using electron global shortcuts API

If you think this could be a new feature, I'd like to work on it 😁
