Final Cut Pro X :: Moving Groups Of Keyframes On Screen?

I recently purchased Final Cut Pro X to edit GoPro videos to share with my friends and family on YouTube. I'm shooting and editing in 1080p @ 60 fps. My experience had gone pretty well, going through the intro screen, introducing each of my cousins and my brother. I had started to fiddle around with keyframes to have the text follow their faces for a cool effect I saw in a video once, and it looked pretty good, but I found it to be incredibly time consuming. So when it got to my part of the intro, I wanted to see if I could try to spice things up and have the effect where you freeze frame shots of yourself at different points in an activity. Well since we shot it all by hand, the shot is incredibly shaky, so I had to try to negate the shakiness by freezing the frame in one area, and it looks good, but took me forever to get the frames right. So now my idea was to just copy the same keyframes I had from before to the next photo, and the next, and so on. But once I figured out the timing, I realized that the image of me is just slightly positioned to the left of where I actually should be. Here's the problem, whenever I try to drag that photo around screen to where my body actually is, it just moves the one, single keyframe, not the whole segment of upwards of 200 individual keyframes I had placed.
