"Enter" as tha name says enters the value in the model, and it seems natural to me that a recompute is performed.
"Tab" only changes the input field, no immediate recompute required.
I like that approach. Simple to use.
Add to that, "Tab" wraps around i.e. if it gets to end end of the prperties then the next tab will move the cursor to the first property.
If the prior stuff was done, the GUI would feel like a typical computer interface for beginners and still have many short-cuts for the advanced user.
GeneFC » This would be another way to create slow response times.
Why would it slow thing down?
I believe I have seen a number of threads in which you complained about slow response times in FreeCAD.
I support the prograrm here by my comments, I try to stay professional and mostly serious. I have stated before, "none of my comments are complaints, just my observations". If it runs slow then I comment that it runs slow, I presume the programmers here want the feedback even though we all mess up every once in a while.
