Compose Key for Chrome OS
This extension adds a Compose Key ("Right Alt") to a US qwerty layout keyboard.
How to enable: after installing the extension, head over to chrome://settings/languages then add English (US), and check the "Compose key" option. If the option does not show up, sign out once and retry the procedure. Switch keyboard layouts with Ctrl+Shift+Space until you hit the Compose key keyboard (symbol: EN*).
How to use:
1. Hit the "Right Alt" key to enter the composition mode (hit again to cancel).
2. Type a valid composition (sequence of characters).

New in 1.4: A few new characters were added and some incorrect sequences were corrected.
