I have a layer that contains multiple keyframes, each keyframe holds and image in it. I want to be able to align the images to the stage in a certain way, but would like to be able to align all the keyframes at once, without having to individually align each one. Is there a way for me to do this? Or would there be a better way to achieve my goal? I have over 300 keyframes with images, so to do each one is just very tedious.
The question wasn't how to do this in Adobe Flash, He was asking about Adobe Animate CC.
On the tool bar on the bottom of the Timeline, there are a bunch of icons. What you are looking for is called "Edit Multiple Frames." It looks like two key frames superimposed. Also (option+shift+E) on Mac.
To select all frames on a layer just adjust the range of keyframes on the top of the timeline and select your desired layer.
