[Elecraft] Powerpoint slides

[Richard Lim]

Hey guys, I just downloaded the Powerpoint slides from the Elecraft 
website and have a question. On one of the slide, they show a K2 with a 
green LED on the front control panel board. Additionally, on the 
faceplate of the K2 there is an additional pushbutton labeled "select" 
to the right of the VFO knob. I'm just wondering what these two 
additions are and if these were unique to Rev A boards or a glimpse of 
what is to come. Thanks.

Rich
