Bob,
Assuming you have the CW signal (in SSB mode) tuned to your sidetone
pitch ---
You will have to re-tune by the amount of your sidetone pitch when
switching to CW.
The K3 (and all other Elecraft transceivers) insert a VFO offset between
SSB and CW equal to the sidetone pitch set into the radio during receive.
SSB has no offset.
In other words, if you are listening to a 600 Hz CW signal when tuned to
a 7040.00 kHz CW signal when in SSB mode (and your sidetone pitch is set
at 600 Hz), you are actually hearing a CW signal at 7039.40 kHz when
tuned to 7040.00 kHz (assuming you have LSB set in SSB mode).
When you switch to CW, you will have to tune to 7039.40 kHz to hear that
same CW signal at 600 Hz - and that is the actual CW transmit frequency.
In other words, in SSB mode, the K2 frequency indication is the
suppressed carrier frequency, but in CW mode it is the transmit
frequency of the CW signal.
To further complicate matters, if you set CW in SSB on in the menu, that
relationship changes. You will transmit offset from the suppressed
carrier frequency by the amount of the sidetone pitch so your signal can
be heard by other stations tuned for SSB.

When I'm in SSB mode and I tune down to the CW frequencies, I can easily
tune in a CW signal. Then, I switch to CW mode, and the CW signal is gone
because I'm on the wrong sideband. Even if I'm on the right sideband, the CW
signal disappears. Shouldn't I be able to switch from SSB to CW and not
lose a CW signal? Am I doing something wrong? Thanks, Bob - W3DK
