Description of TfisHotKey :
This component registers a system-wide key combination to the operating system.When the key combination is created anywhere in the operating system, thiscomponent will get the keypress first and call the OnHotKey event. The applicationdoes not have to be active or visible for the OnHotKey event to be fired.The HotKey property in our implementation consists of a TShortcut so that any key combination you can register in a normal shortcut, you can also register as a HotKey.
