Hello, @Jahor ,

thank you for you report. I dont know if I understood correctly. Do you expect that the model color will be changed imediently after change extruder by the hotkeys?

Correct. At the moment when you press a key nothing happens at all (visually), so it looks like it did not work.

But you have a selected model, so the color of model in scene is green, when unselect model, then model will have color according to extruder color.

That's ok. But it should change the extruder color in the object list immediately.
