Linux (Gnome) - Keyboard Shortcut to Clipboard

This is a simple walkthough on setting up the F12 key to populate the clipboard with the OTP code. This makes logging into GitHub or any other service as simple as pushing F12 and pasting the contents of the clipboard into the 2FA input.

1. You will need xsel or some other CLI that can read the contents of STDOUT to the clipboard:

   sudo apt install -y xsel
   

2. If using Gnome 3 you can just open the control center and navigate to the "Keyboard Shortcuts" with:

   gnome-control-center
   

3. Scroll to the bottom and set a "Custom" keyboard shortcut with the following options:

   Name: OTP (GitHub) Command: sh -c '~/bin/yayo view github | xsel --primary' Shortcut: F12
