-/**
- * If one of the meta shortcuts is detected, process them here:
- *     Meta + Backspace; Meta + Grave; Meta + Left arrow -> generate BACK
- * Most System shortcuts are handled in PhoneWindowManager.java except 'Back' shortcuts. Unlike
- * Back, other shortcuts DO NOT need to be sent to applications and are fully handled by the system.
- * But for Back key and Back shortcuts, we need to send KEYCODE_BACK to applications which can
- * potentially handle the back key presses.
- * Note: We don't send any Meta based KeyEvents to applications, so we need to convert to a KeyEvent
- * where meta modifier is off before sending. Currently only use case is 'Back'.
