This almost works, but there's a funny shifting of the foot that results. A graph of the movement will illustrate why. The graph below shows the motion path of the foot goal. The first two keys have the same value, but there is a slightly curved line between them. This is spline interpolation.
Interpolation is the creation of values between the keys that the user sets.
That's why we have continuously animated motion when we've only set a couple of key poses. But sometimes, as here, we may need to override the spline interpolation to create linear interpolation between the keys. By changing to linear interpolation between the first two keys, the value stays absolutely constant and the foot goal is locked in place until Frame 17.
