skarasuko Your description made me think that this was available in earlier versions, but when I went back and tried it in older versions, it seems that in the animate mode it is not possible to enter mesh edit mode or do tracing via hotkeys.
If you ask me if there is a reason why you can't enter animate mode from a hotkey, I can't think of a clear reason at the moment, but since this was the specification in previous versions, I think it may be a future improvement rather than a bug. I will create an issue so that we do not forget to look into this.
