Hi all, I'm using: XMonad.Layout.WindowNavigation ... and have (from somewhere) the following: , layoutHook = configurableNavigation (navigateColor "#00aa00") $ TL.toggleLayouts (noBorders Full) $ mkToggle (REFLECTX ?? EOT) $ mkToggle (REFLECTY ?? EOT) $ (smartBorders (Grid ||| tiled ||| Full)) When I focus different window, the window borders change color, but i don't know *what* the different colors represent. I tried reading: http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Layout-WindowNavigation.... but didn't find anything relevant. Can someone else enlighten me? :) David
