[Elecraft] CW Keying

[pastormg2 at verizon.net]

This is probably going to be a strange question but I'll ask it anyway.  I don't have a cw key hooked up to the K3 as of yet.  I finally have my microphone hooked up and all the alc and power levels set.  In fact I made my first contact with the K3 on 40 SSB with WP2B.  But I used to set my kenwood ts-480 to cw and would key the microphone and would be able to tune my antenna with my Palstar AT2K with no problems.  But I don't know if I can do the same thing here on the K3.  Any help would be very much appreciated.  Mark KB3Z
