I've only just noticed this. In Console View when you insert an Fx Plug, there's a little readout underneath with darker bars showing a selection of relevant controls which can be dragged up/down without having to open the Fx GUI.
 
Pretty neat I thought.
 
Did I miss this in one of the ezines?
 

Maybe you enabled the feature when playing around with this http://forum.cakewalk.com/FindPost/3340829

Yeah, you nailed it Steve! I forgot I was playing around with that a while ago!
 
Cheers.

Thanks both of you (and Craig for his Channel Tools post), I just learned several more useful things.  I would probably never have stumbled on this by myself.  This has been a good day.
