// keyboard. It drops an "X" button from the top of the screen when user moves
// cursor to the top or long-press on the screen. Pressing that button will exit
// fullscreen.
// This UI is also used as a visual progress indicator when keyboard lock
// requires user to press-and-hold ESC key to exit fullscreen.
