with Version 7 I assume, the Spacebar acts now as a Enter Search which still also works with double clicking the canvas and imho does not bring a big advantage. Now to quickly bake i have to press alt additionally. Maybe i am too much in a hurry but could not find how to change that back. I remember faintly seeing that brought up at some point, that its the way it is now, if so why again?
Also if changing this at all, why not just enabling to type ahead like Rhino? Without the need for extra calling the search.
