Chrome OS
The UK Extended layout in Chrome OS provides all the same combinations as with Windows, but adds many more symbols and dead keys via AltGr. Notes: Dotted circle (◌) is used here to indicate a dead key. The key is the only one that acts as a free-standing dead key and thus does not respond as shown on the key-cap. All others are invoked by AltGr. (°) is a degree sign;  (º) is a masculine ordinal indicator
