module Config where
-- 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, or tiled. You can toggle the layout mode with
-- mod-space.
--
-- 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.
