A long time ago someone showed me that it's possible to add a hotkey to iTerm2 to open the terminal window from anywhere in the system. Till these days I was using ` key as a hotkey. But when having to input ` in markdown or JS I had to use Option + ` which has specific behavior.

I decided to try Caps Lock for a while (as Caps Lock is one of the useless keys on the keyboard).

The issue is that iTerm2 does not recognize the Caps Lock press. So I have to remap in MacOS Caps Lock to Control key.

Go to System Preferences > Keyboard:

1. Select Modifier Keys:

1. Set Caps Lock as Control key:

1. Go to iTerm, System Preferences > Profiles > Select profile > Keys > Configure Hotkey Window:
   

2. Set Double-tap key as Control

Now when you double press Caps Lock (or Ctrl) the iTerm window will popup.
