You will get notification with LOWORD(wParam) == 0 when users sets hotkey.

Subclassed control processes HKM_SETHOTKEY and HKM_GETHOTKEY similarly to
windows' hotkey, in all other it acts just like normal editbox (beware of
standart notifications that occur on text updates!)

Subclass procedure uses GWLP_USERDATA to store internal information. Do not
use it for own purposes.
