Yes that is my goal. Create a hotkey that can do stuff even when the window is not in focus. /me begins searching for GlobalKey to see if that is different! ;)

Well, then this is interesting to me aswell :) Wanted to be able of doing this while back... Gotta check it out more...

Found this on my hd. Not working properly.. dunno why exactly:

# HHOOK SetWindowsHookEx(
#
#     int idHook,
#     HOOKPROC lpfn,
#     HINSTANCE hMod,
#     DWORD dwThreadId
# );

# lpfn
#     [in] Pointer to the hook procedure. If the dwThreadId parameter 
+is zero or specifies
#          the identifier of a thread created by a different process, 
+the lpfn parameter must point
#          to a hook procedure in a dynamic-link library (DLL). Otherw
+ise, lpfn can point to a hook
#          procedure in the code associated with the current process.
# hMod
#     [in] Handle to the DLL containing the hook procedure pointed to 
+by the lpfn parameter.
#          The hMod parameter must be set to NULL if the dwThreadId pa
+rameter specifies a thread
#          created by the current process and if the hook procedure is
+ within the code associated
#          with the current process.
# dwThreadId
#     [in] Specifies the identifier of the thread with which the hook 
+procedure is to be associated.
#          If this parameter is zero, the hook procedure is associated
+ with all existing threads
#          running in the same desktop as the calling thread.

Whatever that means... may be helpfull? Please tell me if you make it work!
