I'd like to keep both keys plugged into the K2 at the same time. How should I
go about that?

Steve,
See page 99 in the K2 manual - add the two diodes and make certain
Auto-Detect is turned on in the menu.

Steve,
Just get a stereo 1/8 male to two stereo 1/8 females y-splitter and plug a key
into each. You'll still have to remember to set the K2 to one key mode or the
other, but that's it. If you want to switch multiple keys between multiple
rigs, you can easily wire up a project box like I did:
Steve - Look at page 99 of the latest (Rev H) manual. The section on CW
Operation shows how the two keys may be connected at the same time. You
might find that a small capacitor connected across the straight key
necessary depending on how much RF you have flying round the shack.

Hi Steve,
You can use a TRS (Tip, Ring,Sleeve) Y cable. At the straight
key you will need to add 2 diodes to to keep isolation between the DOT Dash
leads. Almost any diode will work, common rectifier types in the 4000 series
or small signal 1N914 or 1N4148.
If you want to make the circuit with two diodes for auto detection, then if
you have the possibility use Shottky diodes. This is especially so if you
also want to use an external keyer from time to time in addition to a
straight-key.
See Reliable auto-detect for keyer for Elecraft K2
It is in the manual. Page 99. 73 Geo/W2BPI
