"keyer_multi" was a test compound in Zoltan's machine. So it is not part of the official release.
We have a "Keyer_All" that probably the one that you are looking for. (Common_Studio\Compounds\Keyers)
This compound allows you to pick and setup a keyer.
However if you know which keyer you want to use then we suggest to use the individual keyer compound.
(For example: Keyer_Advanced_B)
