Stopping Follow Path at the beginning I'm mixing animations in NLA editor, and I want start with follow constraint turned off.

For example, I want my character to wave, and then play the walk cycle with follow path. 

The keyframing influence didn't help, the timeline is snapping origin forward.
Okey I found the solution to keyframe follow path curve. You Need Delete Evalution Time in Fcurve.

And Then Manually Set Values Frames and Evalution Time, Click I to keyframe.
