A Maya user asked me if it is possible to do this in blender: slow or accelerate a movement, rotation, etc. by grabbing a frame (not necessarily a keyframe) into the timeline, the graph editor or the dope sheet, and Maya automatically creates a new keyframe.
In blender you can go to any frame where the wanted pose is, insert a keyframe and then move it to the wanted location, but in Maya you can do it by a single click (grabbing the frame where the wanted pose is, to a different location in your timeline) which saves a lot of time when you are animating and need to test different times and speeds.
there is a way to do this in blender? I mean, the one single click stuff? thanks in advance
