Description
It's not immediately apparent what content the "keys" field expects. Currently, it's just an input field, and from the name one would think that copying and pasting a key into that field (and possibly a few of them separated by commas) would get the expected result--when indeed it does not.
We should either change how the field is built/displayed so that it is obviously for creating a list of keys (perhaps a "tag" adding style UI) or at least add a note that states how keys should be formatted when entered into that filed (i.e., ["key"] or ["key","otherkey"]).
