I try to use keyboard shortcuts whenever possible. It would be helpful to me if there were two new keyboard shortcuts. One would put the focus on the Body element for the current page as shown in the navigator. I could then use the arrow keys to navigate up and down the tree. Currently, if I'm in the Style panel, I have to do a mouse click to get to the Navigator. I know I can use the 'z' key to get over there but that's a roundabout way of doing it since it will close the navigator and I have to hit 'z' again to reopen it.
The second keyboard short cut would be similar. It would always put the focus in the Selector section of the Style panel. Once there, I can tab down through the various attributes.
