To set special extension shortcuts like "Ctrl + Tab"
This script only works on the chrome://extensions/shortcuts page.
Open the developer console (F12 -> Console) and copy & paste the content of the special-shortcuts.js.
- Click on the shortcut input you'd like to set the special binding on
- Type the shortcut combination (e.g. Ctrl+Tab) into the prompt input
- Click "OK"
The shortcut should not be set and ready to use.
