STR: Open the Browser Toolbox to the Style Editor view. Try to tab around to the different parts of the Style Editor. Expected: A way to change focus to the different panes (Alt+accelerator to switch to different panes could work) Actual: I found I can hit ctrl+tab to move focus to the file list, then tab to move through the file list but I can't get focus anywhere else on the window such as the frame selector or the media query sidebar.

I should add that Gijs pointed out to me Ctrl-[ and Ctrl-] will cycle through the panes, but I found once I use this and get to the Inspector pane, focus is moved to one of the nodes in the tree and the shortcuts don't work anymore. Also, in comment #0, I used the word "pane" but I mean the different sidebars of the Style Editor (stylesheets and media queries).
