Easiest(!) way to do it is to set MENU | INP | HAND in the K2.

Then get a 3-way RCA jack (female), and connect the outputs of your PC and 
keyer to it. Finally, a jumper cable with an RCA on one end (to the 3-way 
jack) and a 1/8" (3.5mm) STEREO plug with ground from the jumper cable to 
the sleeve of the plug and the hot side of the jumper cable connected to 
the TIP of the plug. Nuthin' connected to the ring of the plug.

Done!
