XPLM_API XPLMHotKeyID XPLMRegisterHotKey( char inVirtualKey, XPLMKeyFlags inFlags, const char * inDescription, XPLMHotKey_f inCallback, void * inRefcon);
This routine registers a hot key. You specify your preferred key stroke virtual key/flag combination, a description of what your callback does (so other plug-ins can describe the plug-in to the user for remapping) and a callback function and opaque pointer to pass in). A new hot key ID is returned. During execution, the actual key associated with your hot key may change, but you are insulated from this.
