How can you change the character case or choose to use numeric mode or predictive text input?
In alpha editing mode (only for Latin characters), a short press of the # key changes the character case (upper/lower), a long press of the # key toggles between numeric mode and alphamode, the 0 key is a space and line feed, and special characters can be found with the * key. A double press of the # key enables/disables predictive text input.
