-// In order to avoid accidental exits when the user presses the exit shortcut by
-// mistake, we require that the user press it twice within a short period of
-// time. During that time we show a popup informing the user of this.
-//
-// Notes:
-//
-// The corresponding accelerator must not be repeatable (see kRepeatableActions
-// in accelerator_table.cc). Otherwise, the "Double Press Exit" will be
-// activated just by holding it down, i.e. probably every time.
-//
-// State Transition Diagrams:
-//
-//  IDLE
-//   | Press
-//  WAIT_FOR_DOUBLE_PRESS action: show ui & start timers
-//   | Press (before time limit )
-//  EXITING action: hide ui, stop timer, exit
-//
-//  IDLE
-//   | Press
-//  WAIT_FOR_DOUBLE_PRESS action: show ui & start timers
-//   | T timer expires
-//  IDLE action: hide ui
