Graph Editor keyframes default to "spline" curves, which smooths out movement as much as automatically possible.

This, however, makes it so that if you have keyframes A and B at one position, and keyframes C and D at a different position, the time between keyframes A and B will have the controls "pull back" in a "lead-up" to the movement of keyframe C. The opposite also applies to the time between keyframes C and D.

If that's the issue, you should select the keyframes that you don't want any movement between, and press 2 on your keyboard to make them use "flat" curves instead. This makes it not do any sort of "lead-up" motion.
