How do you get Steam keys from humble bundle?

I think most people say KEY and means GIFT link. Its simpler to say KEY instead of GIFT LINK.

They are giving away the gift URL.

Probably older bundle keys, Humble and i think other bundle sites have changed to the account linking somewhat recently

you're to young for keys. problem solved

old bundles gave keys

Keys were in the past. Nowadays there is only way through gift link (via humblebundle), other bundles still give keys.
