WM_HOTKEY
The WM_HOTKEY message is posted when the user presses a hot key registered by
the RegisterHotKey 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
Parameters
idHotKey
Value of wParam. Specifies the identifier of the hot key that generated the message. If the
message was generated by a system-defined hot key, the idHotKey parameter will be one of the following values:
Value
| Meaning
| IDHOT_SNAPDESKTOP
| The "snap desktop" hot key was pressed.
| IDHOT_SNAPWINDOW
| The "snap window" hot key was pressed.
|
fuModifiers
Specifies the keys that were to be pressed in combination with the key
specified by the nVirtKey parameter to generate the WM_HOTKEY message. The fuModifiers parameter can be a combination of the following values:
Value
| Meaning
| MOD_ALT
| Either ALT key was held down.
| MOD_CONTROL
| Either CTRL key was held down.
| MOD_SHIFT
| Either SHIFT key was held down.
| MOD_WIN

and are labeled with the Microsoft Windows logo.

Remarks
WM_HOTKEY is unrelated to the WM_GETHOTKEY and WM_SETHOTKEY hot keys. The
WM_HOTKEY message is sent for generic hot keys while the WM_SET\GETHOTKEY messages
relate to window activation hot keys.
