[Elecraft] K3 control hold?

[Andy Faber]

Wayne, et al,
  Is there any way to have a continuous display of one  of the functions 
adjusted by the 4 multifunction knobs, e.g., power, mic, width, etc.?
  The other day I was making amplifier adjustments and had to keep adjusting 
the power knob.  I would have liked the display of power on VFO B to remain 
on, rather than reverting to the normal display after a second. Similarly, 
if one is making audio adjustments, it would be convenient to have comp or 
mic be on continuously.
  Assuming this can't be done now (or am I missing something obvious?), then 
one way to do this would be to add a CTRL HLD function to the various 
displays that are accessible on VFO B when the DISP button is pressed.  Then 
perhaps the most recently adjusted knob parameter should remain displayed 
until another such knob is turned, or until the DISP is changed. This might 
be a Tech Md On function.
