That's right. Details can be found various places, notably

I went through this exercise last summer; if you look at

you'll find the beginning of the thread I started then (not terribly 
interesting in itself, but has a few links of use).

I don't care to switch INP when using various input devices, so I always 
wire tip and ring together on things like this (and straight keys and 
bugs). I made up a little box that has several jacks in parallel, going 
to the required diodes and a paddle input - so I can (and do) have the 
paddles, SK and computer keying all hooked up at the same time.

(See http://www.mail-archive.com/elecraft@mailman.qth.net/msg38462.html)

(I know that some folks have reported problems with the K2's sensing of 
tip/ring for non-paddle keying, but I've never experienced it.)
