The ability to select multiple keyframes at once and move them along the timeline would be helpful. I often find myself inserting a keyframe and having to drag out the existing keyframes after it one by one to adjust the time between frames correctly.
Hi @jhaskell , thank you very much for your request and welcome to our forum! This has already been asked before a few times so it’s on our agenda already! I’ve given the topic a further upvote through your voice.

Got your upvotes!
Yes please!
May I add we should have the choice of selecting a single or multiple keyframe indicators (triangles) on the timeline and be able to simply slide them right or left, maybe with an additional pop-up where you could enter an exact +/- time shift amount in seconds. It would really help to more efficiently and selectively edit the movement speed.
+1 This would be great.
Thanks @Roland_Ganter , @Vincent_2 , forwarding your feedback, thanks a lot!
