Can't add keyframes to Parameters

[photosbyiki]

You have to make sure the tyFlow object is selected when opening the Graph Editor.

oh that's super helpful, thank you, I didn't know that part.  So far I'm able to set keys and now I can also see the keys on the graph.  Now I just need to figure out the odd behaviour from the Spread operator.  Those parameters do some very funky stuff.  For example:- 
I start with a value of 0 and my sphere looks like a sphere.  
I then scrub on the time to a frame and change the value to 100 and add a keyframe.  Sphere is now sliced up
I then scrub further on the timeline and add a final keyframe and change the value back to 0.  What I expect here is the Sphere to be back as it was on frame 0.  However, it doesn't do that.  This operator seems to be doing something funky.
