-- XMonad configuration file by Thomas ten Cate <ttencate@gmail.com>
-- 
-- Works on xmonad-0.8, NOT on 0.7 or below; and of course
-- xmonad-contrib needs to be installed as well
--
-- This is designed to play nice with a standard Ubuntu Hardy installation.
-- It gives you 10 workspaces, available through Alt+F1..F10. You can move
-- windows to a workspace with Win+F1..F10 (and you will automatically switch
-- to that workspace too).
--
-- All workspaces except F9 respect panels and docks.
-- F9 is the fullscreen workspace (for mplayer, etc.).
-- F10 is the instant messaging workspace.
--
-- Pidgin and Skype windows are automatically placed onto the IM workspace.
-- Their contact lists each get a column on the right side of the screen,
-- and all their other windows (chat windows, etc.) go into a grid layout
-- in the remaining space.
-- (This uses a copied and modified version of XMonad.Layout.IM.)
--
-- Keybindings mostly use the Windows key, but some use Alt to mimic other
-- window managers. In general: Alt is used for navigation, Win for modification.
-- Some of the bindings resemble the XMonad defaults, but most don't.
-- The bindings are set up to be comfortable to use on a dvorak keyboard layout.
--
-- Navigation:
-- Alt+F1..F10          switch to workspace
-- Ctrl+Alt+Left/Right  switch to previous/next workspace
-- Alt+Tab              focus next window
-- Alt+Shift+Tab        focus previous window
--
-- Window management:
-- Win+F1..F10          move window to workspace
-- Win+Up/Down          move window up/down
-- Win+C                close window
-- Alt+ScrollUp/Down    move focused window up/down
-- Win+M                move window to master area
-- Win+N                refresh the current window
-- Alt+LMB              move floating window
-- Alt+MMB              resize floating window
-- Alt+RMB              unfloat floating window
-- Win+T                unfloat floating window
--
-- Layout management:
-- Win+Left/Right       shrink/expand master area
-- Win+W/V              move more/less windows into master area
-- Win+Space            cycle layouts
--
-- Other:
-- Win+Enter            start a terminal
-- Win+R                open the Gnome run dialog
-- Win+Q                restart XMonad
-- Win+Shift+Q          display Gnome shutdown dialog
