Copy - Paste Keyframe Attributes (all at once)

Hi, towards the bottom of the Roadmap is something regarding keyframes, but not sure if this is what it means. Also, if its already available please show me where (I dont think this is though)

It would be great to select the keyframe (red dot) have a copy option, then move the playhead to the prefered location, and paste the keyframe (so it coppies all the attributes in one go).

And building on from there, selecting multiple keyframes (i.e. 10 red dots at once) :smiley:

I have a large project on at the moment and this would be an incredible time saver!
