[Elecraft] K3 control questions

[Brett gazdzinski]

I was looking at the K3 pix and have a few questions
while I wait the 7 days....maybe a field tester can clue me in...

What displays do you get when you press and/or hold the disp/meter
button? What does that button do?

What is the cvp control? 

What happens with the NB and NR buttons?
I assume a push turns them on/off, what does hold do, 
what display changes do you get, options?

The other basic buttons I think I can guess what they do..

On a side note, the heat sink for the finals looks like
it could be made a lot bigger and still fit inside the K3
space...at least from the pictures....
