 In Subscription mode, you bypass AHK's hotkey system completely, and Interception notifies you of key events via callbacks.  
 All forms of input are supported in Subscription Mode.  
 Subscription Mode overrides Context Mode - that is, if a key on a keyboard has been subscribed to with Subscription Mode, then Context Mode will not fire for that key on that keyboard.  
+Each Subscribe endpont also has a corresponding Unsubscribe endpoint, which removes the subscription and any block associated with it.
