Detailed description
| The modifier keys (i.e., Shift, Ctrl, Function, Chr) in devices with a full keyboard do not generate separate key press events. The MIDP key event API (keyPressed/keyRepeated/keyReleased callback methods) does not have proper full keyboard mechanisms so the key codes are only available for character keys. The MIDP key API does not have a mechanism to indicate modifiers in key events so separate presses of modifier keys do not generate separate events in S60 Java. Key combinations like Shift+A or Chr+A will create appropriate character key events.
A special key, for example the Chr key which normally triggers a user interface for special character selection, will deliver only low-level key events if it is combined with some other key. Note also that in low-level key input it is not possible to trigger key events for more than one special character or accented character with the Chr key combined with some other key. Keystrokes in which the Chr key is combined with other keys will only result in the same key codes repeatedly in consecutive key presses regardless how many times the same key combination is being pressed.
