module Config where
--
-- xmonad bindings follow mostly the dwm/wmii conventions:
--
-- key combination action
--
-- mod-shift-return new xterm
-- mod-p launch dmenu
-- mod-shift-p launch gmrun
--
-- mod-space switch tiling mode
--
-- mod-tab raise next window in stack
-- mod-j
-- mod-k
--
-- mod-h decrease the size of the master area
-- mod-l increase the size of the master area
--
-- mod-shift-c kill client
-- mod-shift-q exit window manager
-- mod-shift-ctrl-q restart window manager ('xmonad' must be in $PATH)
--
-- mod-return cycle the current tiling order
--
-- mod-1..9 switch to workspace N
-- mod-shift-1..9 move client to workspace N
--
-- mod-w,e,r switch to physical/Xinerama screen 1, 2 or 3.
--
-- xmonad places each window into a "workspace." Each workspace can have
-- any number of windows, which you can cycle though with mod-j and mod-k.
-- Windows are either displayed full screen, tiled horizontally, or tiled
-- vertically. You can toggle the layout mode with mod-space, which will
-- cycle through the available modes.
--
-- You can switch to workspace N with mod-N. For example, to switch to
-- workspace 5, you would press mod-5. Similarly, you can move the current
-- window to another workspace with mod-shift-N.
--
-- When running with multiple monitors (Xinerama), each screen has exactly
-- 1 workspace visible. When xmonad starts, workspace 1 is on screen 1,
-- workspace 2 is on screen 2, etc. If you switch to a workspace which is
-- currently visible on another screen, xmonad simply switches focus to
-- that screen. If you switch to a workspace which is *not* visible, xmonad
-- replaces the workspace on the *current* screen with the workspace you
-- selected.
--
-- For example, if you have the following configuration:
--
-- Screen 1: Workspace 2
-- Screen 2: Workspace 5 (current workspace)
--
-- and you wanted to view workspace 7 on screen 1, you would press:
--
-- mod-2 (to select workspace 2, and make screen 1 the current screen)
-- mod-7 (to select workspace 7)
--
-- Since switching to the workspace currently visible on a given screen is
-- such a common operation, shortcuts are provided: mod-{w,e,r} switch to
-- the workspace currently visible on screens 1, 2, and 3 respectively.
-- Likewise, shift-mod-{w,e,r} moves the current window to the workspace on
-- that screen. Using these keys, the above example would become mod-w
-- mod-7.
