Run zLoader once you have started up StarCraft to load the hack.

F11 is to toggle through three levels of unit attack range hack: 1. All Units 2. Select Units 3. No Circles

Delete toggles location viewer hack on and off

If you are using this in conjunction with Oblivion, load Oblivion first, and then load this, or the hotkeys will not work for this.
To toggle the location hack with Oblivion loaded, and not pop up the chat history, use Ctrl+Delete.
If you are playing on Battle.Net, this must be loaded after entering Battle.Net, not before.
If you start SC with zLoader, the hack will still function, but you won't be able to get on B.net, and hotkeys won't toggle anything.
