Hate to Ask...

I know this is a mega-noob question (at least I think it is), but I have done a few searches and could not unearth the answer.
*drums*
For the weapon set bar thing (F1, F2 etc.)... how do you "activate" all four sets? On my screen there is only an F1 slot - just wondering how to "turn on" (or whatever) all of the slots?

Thanks for any help, and sorry if this has been asked/answered in the past -_-

Open your Inventory - just below the pic of your character there's a "Weapon Sets" button - click it and a window pops up - check the slots you want to appear.

Alright thanks, guess I could have looked a bit harder >.<

Dont worry about it , its something that can and is easily missed by a few people.
