Rigify panels in graph editor

Hi newbie to Blender, coming from Lightwave. I’ve rigged a character with Rigify and started to pose it. I then noticed that the arms were stretching when using IK. Which I did not want. I then went to the Rigify panel and set IK stretch to 0 but realized that I had set a keyframe for it. Is there a way to see the keyframes for the items in this panel (IK Stretch, Pole vector, IK follow,etc.) in the graph editor or dope sheet? Thanks
