/***************************************************************************
 * VIRTUAL KEY CODES
 ***************************************************************************/
/*
 * These are cross-platform defines for every distinct keyboard press on the 
 * computer. Every physical key on the keyboard has a virtual key code.  So 
 * the "two" key on the  top row of the main keyboard has a different code 
 * from the "two" key on the numeric key pad.  But the 'w' and 'W' character 
 * are indistinguishable by virtual key code  because they are the same 
 * physical key (one with and one without the shift key). 
 * 
 * Use virtual key codes to detect keystrokes that do not have ASCII 
 * equivalents, allow the user to map the numeric keypad separately from the 
 * main keyboard, and detect control key and other modifier-key combinations 
 * that generate ASCII control key sequences (many of which are not available 
 * directly via character keys in the SDK).			 
 * 
 * To assign virtual key codes we started with the Microsoft set but made some 
 * additions and changes.  A few differences: 
 * 
 * 1. Modifier keys are not available as virtual key codes.  You cannot get 
 * distinct modifier press and release messages.  Please do not try to use 
 * modifier keys as regular keys; doing so will almost certainly interfere 
 * with users' abilities to use the native x-plane key bindings. 
 * 
 * 2. Some keys that do not exist on both Mac and PC keyboards are removed. 
 * 
 * 3. Do not assume that the values of these keystrokes are interchangeable 
 * with MS v-keys.
