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.
