Duplicating keyframes in After Effects I've made a basic animation where an element quickly changes position multiple times, e.g:


Top left corner
Middle
Top left corner
Bottom right corner


I'm trying to duplicate these keyframes a couple times so that the animation lasts longer.

Is there a way to do this? I've read up on copying / pasting keyframes to different layers, but I can't find a way to paste them onto the same layer
Click the layer were your made the keyframes
Press U or P to reveal the keyframes
Highlight the keyframes. You will know it's highlighted since the color of the keyframes is colored blue(see screenshot below)

CTRL + C to copy the keyframes
Move your time indicator to the next time you wanted
CTRL + V to paste the keyframe
Note: You need to properly copy the Start and End of the keyframe so that you won't mess up the animation
