Thank you for response π
Nate, its really possible. Was searching Blender forums looking for overlapping/offset but couldnt find anything about this.
Harald, I was trying to move them like this and its fine but cant move them like in the spine offset's tool. I mean to move keyframes only in the start-end area and when they reach the end of timeline, start appear on its start.
Generally, I dont need to just move keyframes, I need exacly what Offset does in the Spine.
