Keyboard 468 was a 18-keys keyboard.
The letters are sorted by frequency in the English language, and their likeliness to follow the last input character.
The purpose of this experimental keyboard is to have a keyboard displaying large letters, making it so you only ever need to type using the two rows at the top, maximizing the space and allowing for big large letters. The hidden letters are accessible through the alt key, alongside symbols and numbers.
As of March 2019, this application is no longer maintained.
