Actually I short-changed that feature.
Get within ~100 Hz and the K3 automatically
zero beats for you. From the FAQ:
##################################################Speaking of CW ..
is there a method for spotting?
There are two methods.
The first is the normal spotting tone that you tune for zero beat.
TAP the SPOT switch to toggle the tone on and off.
There is also a feature called CWT. You press this button and the
right half of the S Meter display becomes a zero-center tuning meter.
You tune the signal in according to this bar graph. When you are
close (within a hundred Hz or so either way) you can either finish
tuning yourself, or TAP the SPOT button and voila -- the K3 will tune
itself to zero beat. The same feature works in data modes. This is
great for tuning in PSK31 and TTY signals.
There's a front-panel knob that controls the volume level of the spotting tone.

Also here's a fun website to test how well you can
match two 500 Hz tones (like you would when zero-beating
a 500 Hz CW pitch):
