WM_HOTKEY TGAX0Z

The WM_HOTKEY message is posted when the user presses a hot key registered by the RegisterHotKey1GLLZLD function. The message is placed at the top of the message queue associated with the thread that registered the hot key.

WM_HOTKEY

idHotKey = (int) wParam; // identifier of hot key

fuModifiers = (UINT) LOWORD(lParam); // key-modifier flags

uVirtKey = (UINT) HIWORD(lParam); // virtual-key code

Value	Meaning
IDHOT_SNAPDESKTOP	The snap desktop hot key was pressed.
IDHOT_SNAPWINDOW	The snap window hot key was pressed.
