- Click the Settings icon.On the left panel, scroll down to the Device section.
- On the right panel, select Keyboard. This will bring up the Keyboard settings. Click on the toggle to enable Treat top-row keys as function keys.
Hold the search button (which is located where the caps lock button would normally be) while pressing a top row key
e.g. The Refresh button will be F3, reduce brightness will be F6, etc.
