Notes

• Wireless - When toggling off, NetworkManager reports that WiFi is disabled but the connection remains active. When it's toggled back on, NetworkManager reports that the connection is disconnected but it remains active and fewer wireless networks are listed as available than before.
• Numlock - While the scroll lock key does not actually toggle scroll lock, one is still able to input symbols in blue by holding down the Fn button and pressing the relevant key.
