/*
About Key Events. Because the Android Spec doesn't require
soft keyboards to dispatch key events not all keyboard implementations
across Android will trigger these actions.
Currently we use the following function to translate keycodes for
special character, capital letters, and digits.
keycode 123 (F12) is used as a single digit capslock button which
when sent to the miniclient before a char will act accordingly.
