New to the Bundle Stuff

Well when buying bundles you usually get separate keys so you can just use the keys for the games you dont have

Depends on the Humble Bundle. In some bundles, the keys all come in one batch, so it's activate all or activate none (you will get no spare keys if you already own some of the games). Examples would be the Deep Silver Bundle. Other bundles, all keys are separate, so you can pick and choose the ones you want to activate and giveaway the others to whomever you wish.

Any idea how the indie bundle comes on humblebundle?
