Although unlikely, virtual key code values MAY overlap real key code values. Virtual
key codes always include the commandKeyMask modifier as a distinguishing
characteristic of their "virtualness."

There is no table. Instead, the macros TxtCharIsVirtual() or TxtGlueCharIsVirtual()
should be used to distinguish virtual from real key events.
