When using the keyboard to edit the values within the box model view it is not obvious which value will be edited. There is no focus ring around the value where the inline editor will be opened when hitting Enter and it is not obvious that Up/Down allow you to cycle through the possible box model properties. Therefore, the focus ring should always be displayed at the right element and tabbing through the values should go down from the border values to the width and height of the element like its working within Firebug. E.g. when you tabbed through all margin values the inline editor should switch to the border values, then to the padding values and finally to the width and height values. Sebastian
