The idea of transforming the selection box in the graph editor similar to how it works in Photoshop is an interesting suggestion. Currently, in Spine, you can manipulate the selection box in the graph editor by holding the box selection for a second, which allows you to scale the keys. This functionality is similar to the mechanics used in the Dopesheet and Graph, where you can scale on both the X and Y axes. While the specific feature you mentioned isn't available yet, the existing tools provide some flexibility in transforming selections.

Ankoss88 Hmmm, that is an interesting idea, but I have never seen software that has the ability to do such a transformation on box-selected keys, so I can't really imagine how useful it would be in practice. When would you actually want to do this? I would like to hear about the use cases you envision.
