window manager. If it does not, please check https://www.reddit.com/r/i3wm/
== Default keybindings
For the "too long; didn’t read" people, here is an overview of the default
-keybindings (click to see the full size image):
+keybindings (click to see the full-size image):
*Keys to use with $mod (Alt):*
Throughout this guide, the keyword +$mod+ will be used to refer to the
configured modifier. This is the Alt key (+Mod1+) by default, with the Windows
-key (+Mod4+) being a popular alternative.
+key (+Mod4+) being a popular alternative that largely prevents conflicts with
+application-defined shortcuts.
=== Opening terminals and moving around
=== The tree consists of Containers
-The building blocks of our tree are so called +Containers+. A +Container+ can
+The building blocks of our tree are so-called +Containers+. A +Container+ can
host a window (meaning an X11 window, one that you can actually see and use,
like a browser). Alternatively, it could contain one or more +Containers+. A
simple example is the workspace: When you start i3 with a single monitor, a
you open a new terminal, it will open below the current one.
So, how can you open a new terminal window to the *right* of the current one?
-The solution is to use +focus parent+ (+$mod+a+ by default), which will focus the +Parent Container+ of
+The solution is to use +focus parent+, which will focus the +Parent Container+ of
the current +Container+. In this case, you would focus the +Vertical Split
Container+ which is *inside* the horizontally oriented workspace. Thus, now new
windows will be opened to the right of the +Vertical Split Container+:
=== The floating modifier
To move floating windows with your mouse, you can either grab their titlebar
-or configure the so called floating modifier which you can then press and
+or configure the so-called floating modifier which you can then press and
click anywhere in the window itself to move it. The most common setup is to
use the same key you use for managing windows (Mod1 for example). Then
you can press Mod1, click into a window using your left mouse button, and drag

-=== Border style for new windows
+=== Default border style for new windows
This option determines which border style new windows will have. The default is
-+normal+. Note that new_float applies only to windows which are starting out as
++normal+. Note that default_floating_border applies only to windows which are starting out as
floating windows, e.g., dialog windows, but not windows that are floated later on.
*Syntax*:
---------------------------------------------
-new_window normal|none|pixel
-
new_window normal|pixel <px>
-new_float normal|none|pixel
-
new_float normal|pixel <px>
+default_border normal|none|pixel
+
default_border normal|pixel <px>
+default_floating_border normal|none|pixel
+
default_floating_border normal|pixel <px>
---------------------------------------------
+Please note that +new_window+ and +new_float+ have been deprecated in favor of the above options
+and will be removed in a future release. We strongly recommend using the new options instead.
+
*Example*:
---------------------
-new_window pixel
+default_border pixel
---------------------
The "normal" and "pixel" border styles support an optional border width in
*Example*:
---------------------
-# The same as new_window none
-new_window pixel 0
+# The same as default_border none
+default_border pixel 0
# A 3 px border
-new_window pixel 3
+default_border pixel 3
---------------------
window (mapping means actually displaying it on the screen), you’d need to have
to match on 'Firefox' in this case.
+You can also assign a window to show up on a specific output. You can use RandR
+names such as +VGA1+ or names relative to the output with the currently focused
+workspace such as +left+ and +down+.
+
Assignments are processed by i3 in the order in which they appear in the config
file. The first one which matches the window wins and later assignments are not
considered.
*Syntax*:
------------------------------------------------------------
-assign <criteria> [→] [workspace] <workspace>
+assign <criteria> [→] [workspace] [number] <workspace>
+assign <criteria> [→] output left|right|up|down|primary|<output>
------------------------------------------------------------
*Examples*:
# Assignment to a named workspace
assign [class="^URxvt$"] → work
+# Assign to the workspace with number 2, regardless of name
+assign [class="^URxvt$"] → number 2
+
+# You can also specify a number + name. If the workspace with number 2 exists, assign will skip the text part.
+assign [class="^URxvt$"] → number "2: work"
+
# Start urxvt -name irssi
assign [class="^URxvt$" instance="^irssi$"] → 3
+
+# Assign urxvt to the output right of the current one
+assign [class="^URxvt$"] → output right
+
+# Assign urxvt to the primary output
+assign [class="^URxvt$"] → output primary

+Note that you might not have a primary output configured yet. To do so, run:
+-------------------------
+xrandr --output <output> --primary
+-------------------------
+
+Also, the arrow is not required, it just looks good :-). If you decide to
use it, it has to be a UTF-8 encoded arrow, not `->` or something like that.
To get the class and instance, you can use +xprop+. After clicking on the
=== Focus wrapping
-When being in a tabbed or stacked container, the first container will be
-focused when you use +focus down+ on the last container -- the focus wraps. If
-however there is another stacked/tabbed container in that direction, focus will
-be set on that container. This is the default behavior so you can navigate to
-all your windows without having to use +focus parent+.
+By default, when in a container with several windows or child containers, the
+opposite window will be focused when trying to move the focus over the edge of
+a container (and there are no other containers in that direction) -- the focus
+wraps.
+
+If desired, you can disable this behavior by setting the +focus_wrapping+
+configuration directive to the value +no+.
+
+When enabled, focus wrapping does not occur by default if there is another
+window or container in the specified direction, and focus will instead be set
+on that window or container. This is the default behavior so you can navigate
+to all your windows without having to use +focus parent+.
If you want the focus to *always* wrap and you are aware of using +focus
-parent+ to switch to different containers, you can use the
-+force_focus_wrapping+ configuration directive. After enabling it, the focus
-will always wrap.
+parent+ to switch to different containers, you can instead set +focus_wrapping+
+to the value +force+.
*Syntax*:
---------------------------
-force_focus_wrapping yes|no
----------------------------
+focus_wrapping yes|no|force
-*Example*:
-------------------------
+# Legacy syntax, equivalent to "focus_wrapping force"
force_focus_wrapping yes
-------------------------
+---------------------------
+
+*Examples*:
+-----------------
+# Disable focus wrapping
+focus_wrapping no
+
+# Force focus wrapping
+focus_wrapping force

=== Forcing Xinerama
*Syntax*:
----------------------------
-bindsym button<n> <command>
+bindsym [--release] button<n> <command>
----------------------------
*Example*:
bar {
# disable clicking on workspace buttons
bindsym button1 nop
+ # Take a screenshot by right clicking on the bar
+ bindsym --release button3 exec --no-startup-id import /tmp/latest-screenshot.png
# execute custom script when scrolling downwards
bindsym button5 exec ~/.i3/scripts/custom_wheel_down
}
To change focus, you can use the +focus+ command. The following options are
available:
+<criteria>::
+ Sets focus to the container that matches the specified criteria.
+ See <<command_criteria>>.
left|right|up|down::
Sets focus to the nearest container in the given direction.
parent::
*Syntax*:
----------------------------------------------
+<criteria> focus
focus left|right|down|up
focus parent|child|floating|tiling|mode_toggle
focus output left|right|up|down|primary|<output>
*Examples*:
-------------------------------------------------
+# Focus firefox
+bindsym $mod+F1 [class="Firefox"] focus
+
# Focus container on the left, bottom, top, right
bindsym $mod+j focus left
bindsym $mod+k focus down
*Syntax*:
-------------------------------------------------------
resize grow|shrink <direction> [<px> px [or <ppt> ppt]]
-resize set <width> [px] <height> [px]
+resize set <width> [px | ppt] <height> [px | ppt]
-------------------------------------------------------
Direction can either be one of +up+, +down+, +left+ or +right+. Or you can be
how many pixels a *floating container* should be grown or shrunk (the default
is 10 pixels). The ppt argument means percentage points and specifies by how
many percentage points a *tiling container* should be grown or shrunk (the
-default is 10 percentage points). Note that +resize set+ will only work for
-floating containers.
+default is 10 percentage points).
+
+Notes about +resize set+: a value of 0 for <width> or <height> means "do
+not resize in this direction", and resizing a tiling container by +px+ is not
+implemented.
It is recommended to define bindings for resizing in a dedicated binding mode.
See <<binding_modes>> and the example in the i3
*Examples*:
---------------------------------------
# Read 1 character and mark the current window with this character
-bindsym $mod+m exec i3-input -p 'mark ' -l 1 -P 'Mark: '
+bindsym $mod+m exec i3-input -F 'mark %s' -l 1 -P 'Mark: '
# Read 1 character and go to the window with the character
-bindsym $mod+g exec i3-input -p 'goto ' -l 1 -P 'Goto: '
+bindsym $mod+g exec i3-input -F '[con_mark="%s"] focus' -l 1 -P 'Goto: '
