Overview

How can I detect the "ABC" key?

Description

What are the TKeyEvent.iCode and iScanCode values of the "ABC" (pencil) key?

Solution

The ABC key is mapped to the Shift modifier key in S60. The following code detects it:
 TKeyResponse CMyClass::OfferKeyEventL(...)
    {
    TBool shiftKeyPressed = (aKeyEvent.iModifiers & EModifierShift);
    ...
    }
The keycode and scancodes depend on the key pressed with the Shift key. The following code detects Shift+OK combination in a listbox's OfferKeyEventL(), where it is used to mark a listbox item:
TKeyResponse CMyBusinessClass::OfferKeyEventL(...)
    {
    TBool shiftKeyPressed = (aKeyEvent.iModifiers & EModifierShift);
    if (shiftKeyPressed && aKeyEvent.iCode==EKeyOK)
        DoSomething();
    ...
    }
