[heathayf] Many keypress soft keyboard

An on-screen keyboard displays only a few large buttons, good by Fitts's Law.  However, each button is labeled with the many characters, taking advantage of very high pixel density in recent mobile displays.

Pushing a button reveals more large buttons for some of those characters.  Most characters are two keystrokes, some three.  The positions are constant, allowing the user to touch type rapidly.
