This is super annoying. I create a keyframe, let's say a motion keyframe. Set it to 50. Then create another one, set it to 100 and put it at the end of the clip. Then I scroll to the second keyframe and suddenly, Premiere has switched me to the next clip in the timeline for some reason. This is so annoying. Even moreso when I'm using my mouse to move the scrubber around, sometimes it juts me all the way to the end of the timeline. I can't imagine a scenario where I would want this behavior.
