=== Opening terminals and moving around
One very basic operation is opening a new terminal. By default, the keybinding

-pressing $mod+Enter, a new terminal will be opened. It will fill the whole
-space available on your screen.

To move the focus between the two terminals, you can use the direction keys
which you may know from the editor +vi+. However, in i3, your homerow is used
for these keys (in +vi+, the keys are shifted to the left by one for
-compatibility with most keyboard layouts). Therefore, +$mod+J+ is left, +$mod+K+
-is down, +$mod+L+ is up and `$mod+;` is right. So, to switch between the
-terminals, use +$mod+K+ or +$mod+L+. Of course, you can also use the arrow keys.

At the moment, your workspace is split (it contains two terminals) in a
specific direction (horizontal by default). Every window can be split

It is only natural to use so-called +Split Containers+ in order to build a
layout when using a tree as data structure. In i3, every +Container+ has an
On first start (and on all following starts, unless you have a configuration
file), i3 will offer you to create a configuration file. You can tell the
-wizard to use either Alt (Mod1) or Windows (Mod4) as modifier in the config
+wizard to use either Alt (+Mod1+) or Windows (+Mod4+) as modifier in the config
file. Also, the created config file will use the key symbols of your current
keyboard layout. To start the wizard, use the command +i3-config-wizard+.
Please note that you must not have +~/.i3/config+, otherwise the wizard will
exit.
+Since i3 4.0, a new configuration format is used. i3 will try to automatically
+detect the format version of a config file based on a few different keywords,
+but if you want to make sure that your config is read with the new format,
+include the following line in your config file:

=== Keyboard bindings
A keyboard binding makes i3 execute a command (see below) upon pressing a
alias for Group2.
[[mousebindings]]
-
=== Mouse bindings
A mouse binding makes i3 execute a command upon pressing a specific mouse
can configure mouse bindings in a similar way to key bindings.
*Syntax*:
--------------------------------------------------------------------------------
-bindsym [--release] [--border] [--whole-window] [<Modifiers>+]button<n> command
--------------------------------------------------------------------------------
+----------------------------------------------------------------------------------------------------
+bindsym [--release] [--border] [--whole-window] [--exclude-titlebar] [<Modifiers>+]button<n> command
+----------------------------------------------------------------------------------------------------
By default, the binding will only run when you click on the titlebar of the
window. If the +--release+ flag is given, it will run when the mouse button
of the window is clicked, with the exception of the border. To have a bind run
when the border is clicked, specify the +--border+ flag.
+If the +--exclude-titlebar+ flag is given, the titlebar will not be considered
+for the keybinding.
+
*Examples*:
--------------------------------
# The middle button over a titlebar kills the window
--------------------------------
[[binding_modes]]
-
=== Binding modes
You can have multiple sets of bindings by using different binding modes. When
*Example*:
------------------------------------------------------------------------
-# Press $mod+o followed by either f, t, Esc or Return to launch firefox,
+# Press $mod+o followed by either f, t, Escape or Return to launch firefox,
# thunderbird or return to the default mode, respectively.

-=== Arbitrary commands for specific windows (for_window)
-
[[for_window]]
+=== Arbitrary commands for specific windows (for_window)
With the +for_window+ command, you can let i3 execute any command when it
encounters a specific window. This can be used to set windows to floating or to
The valid criteria are the same as those for commands, see <<command_criteria>>.
-=== Don't focus window upon opening
-
[[no_focus]]
+=== Don't focus window upon opening
When a new window appears, it will be focused. The +no_focus+ directive allows preventing
this from happening and must be used in combination with <<command_criteria>>.

=== Variables
As you learned in the section about keyboard bindings, you will have
you should create a little script which generates a configuration file and run
it before starting i3 (for example in your +~/.xsession+ file).
-=== Automatically putting clients on specific workspaces
+Also see <<xresources>> to learn how to create variables based on resources
+loaded from the X resource database.
+
+[[xresources]]
+=== X resources
+
+<<variables>> can also be created using a value configured in the X resource
+database. This is useful, for example, to avoid configuring color values within
+the i3 configuration. Instead, the values can be configured, once, in the X
+resource database to achieve an easily maintainable, consistent color theme
+across many X applications.
+
+Defining a resource will load this resource from the resource database and
+assign its value to the specified variable. A fallback must be specified in
+case the resource cannot be loaded from the database.
+
+*Syntax*:
+----------------------------------------------------
+set_from_resource $<name> <resource_name> <fallback>
+----------------------------------------------------
+
+*Example*:
+----------------------------------------------------------------------------
+# The ~/.Xresources should contain a line such as
+# *color0: #121212
+# and must be loaded properly, e.g., by using
+# xrdb ~/.Xresources
+# This value is picked up on by other applications (e.g., the URxvt terminal
+# emulator) and can be used in i3 like this:
+set_from_resource $black i3wm.color0 #000000
+----------------------------------------------------------------------------
[[assign_workspace]]
+=== Automatically putting clients on specific workspaces
To automatically make a specific window show up on a specific workspace, you
can use an *assignment*. You can match windows by using any criteria,
*Syntax*:
------------------------------------------------------------
-assign <criteria> [→] [workspace] <workspace>
+assign <criteria> [→] [workspace] [number] <workspace>
------------------------------------------------------------
*Examples*:
# Assignment to a named workspace
assign [class="^URxvt$"] → 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
----------------------
See <<command_chaining>> for details on the special meaning of +;+ (semicolon)
and +,+ (comma): they chain commands together in i3, so you need to use quoted
-strings if they appear in your command.

=== Focus follows mouse
-By default, window focus follows your mouse movements. However, if you have a

[[line_continuation]]
-
=== Line continuation
Config files support line continuation, meaning when you end a line in a
backslash character (`\`), the line-break will be ignored by the parser. This
feature can be used to create more readable configuration files.
+Commented lines are not continued.

=== Tray output
You can configure on which output (monitor) the icons should be displayed or
you can turn off the functionality entirely.
+You can use multiple +tray_output+ directives in your config to specify a list
+of outputs on which you want the tray to appear. The first available output in

The criteria which are currently implemented are:
class::
Compares the window class (the second part of WM_CLASS). Use the
- special value +__focused__+ to match all windows having the same window
+ special value +\_\_focused__+ to match all windows having the same window
class as the currently focused window.
instance::
Compares the window instance (the first part of WM_CLASS). Use the
- special value +__focused__+ to match all windows having the same window
+ special value +\_\_focused__+ to match all windows having the same window
instance as the currently focused window.
window_role::
Compares the window role (WM_WINDOW_ROLE). Use the special value
- +__focused__+ to match all windows having the same window role as the
+ +\_\_focused__+ to match all windows having the same window role as the
currently focused window.
window_type::
Compare the window type (_NET_WM_WINDOW_TYPE). Possible values are
+normal+, +dialog+, +utility+, +toolbar+, +splash+, +menu+, +dropdown_menu+,
- +popup_menu+ and +tooltip+.
+ +popup_menu+, +tooltip+ and +notification+.
id::

=== Executing applications (exec)
What good is a window manager if you can’t actually start any applications?

and Qt using applications seem to be, though), you will end up with a watch
cursor for 60 seconds.
+[[exec_quoting]]
+If the command to be executed contains a +;+ (semicolon) and/or a +,+ (comma),
+the entire command must be quoted. For example, to have a keybinding for the
+shell command +notify-send Hello, i3+, you would add an entry to your
+configuration file like this:
+
+*Example*:
+------------------------------
+# Execute a command with a comma in it
+bindsym $mod+p exec "notify-send Hello, i3"
+------------------------------
+
+If however a command with a comma and/or semicolon itself requires quotes, you
+must escape the internal quotation marks with double backslashes, like this:
+
+*Example*:
+------------------------------
+# Execute a command with a comma, semicolon and internal quotes
+bindsym $mod+p exec "notify-send \\"Hello, i3; from $USER\\""
+------------------------------
+
=== Splitting containers
The split command makes the current window a split container. Split containers
If you apply this command to a split container with the same orientation,
nothing will happen. If you use a different orientation, the split container’s
-orientation will be changed (if it does not have more than one window). Use
-+layout toggle split+ to change the layout of any split container from splitv
-to splith or vice-versa.
+orientation will be changed (if it does not have more than one window).
+The +toggle+ option will toggle the orientation of the split container if it
+contains a single window. Otherwise it makes the current window a split
+container with opposite orientation compared to the parent container.
+Use +layout toggle split+ to change the layout of any split container from
+splitv to splith or vice-versa. You can also define a custom sequence of layouts
+to cycle through with +layout toggle+, see <<manipulating_layout>>.
*Syntax*:
--------------------------
-split vertical|horizontal
--------------------------
+--------------------------------
+split vertical|horizontal|toggle
+--------------------------------
*Example*:
-------------------------------
+-------------------------------
bindsym $mod+v split vertical
bindsym $mod+h split horizontal
-------------------------------
+bindsym $mod+t split toggle
+-------------------------------
=== Manipulating layout
or +layout splith+ to change the current container layout to splith/splitv,
stacking, tabbed layout, splitv or splith, respectively.
+Specify up to four layouts after +layout toggle+ to cycle through them. Every
+time the command is executed, the layout specified after the currently active
+one will be applied. If the currently active layout is not in the list, the
+first layout in the list will be activated.
+
To make the current window (!) fullscreen, use +fullscreen enable+ (or
+fullscreen enable global+ for the global mode), to leave either fullscreen
mode use +fullscreen disable+, and to toggle between these two states use
--------------------------------------------
layout default|tabbed|stacking|splitv|splith
layout toggle [split|all]
+layout toggle [split|tabbed|stacking|splitv|splith] [split|tabbed|stacking|splitv|splith]…

*Examples*:
# Toggle between stacking/tabbed/splith/splitv:
bindsym $mod+x layout toggle all
+# Toggle between stacking/tabbed/splith:
+bindsym $mod+x layout toggle stacking tabbed splith
+
+# Toggle between splitv/tabbed
+bindsym $mod+x layout toggle splitv tabbed
+
+# Toggle between last split layout/tabbed/stacking
+bindsym $mod+x layout toggle split tabbed stacking
+
# Toggle fullscreen
bindsym $mod+f fullscreen toggle

[[_focusing_moving_containers]]
-
=== Focusing containers
To change focus, you can use the +focus+ command. The following options are
----------------------------------------------
focus left|right|down|up
focus parent|child|floating|tiling|mode_toggle
-focus output left|right|up|down|<output>
+focus output left|right|up|down|primary|<output>
----------------------------------------------
*Examples*:
# Focus the big output
bindsym $mod+x focus output HDMI-2
+
+# Focus the primary output
+bindsym $mod+x focus output primary
-------------------------------------------------
+-------------------------------
+Note that you might not have a primary output configured yet. To do so, run:
+-------------------------
+xrandr --output <output> --primary
+-------------------------
+
=== Moving containers
Use the +move+ command to move a container.
# Moves the container either to a specific location
# or to the center of the screen. If 'absolute' is
# used, it is moved to the center of all outputs.
-move [absolute] position [[<px> px] [<px> px]|center]
+move [absolute] position <pos_x> [px] <pos_y> [px]
+move [absolute] position center
# Moves the container to the current position of the
# mouse cursor. Only affects floating containers.
bindsym $mod+m move position mouse
-------------------------------------------------------
+=== Swapping containers
+
+Two containers can be swapped (i.e., move to each other's position) by using
+the +swap+ command. They will assume the position and geometry of the container
+they are swapped with.
+
+The first container to participate in the swapping can be selected through the
+normal command criteria process with the focused window being the usual
+fallback if no criteria are specified. The second container can be selected
+using one of the following methods:
+
++id+:: The X11 window ID of a client window.
++con_id+:: The i3 container ID of a container.
++mark+:: A container with the specified mark, see <<vim_like_marks>>.
+
+Note that swapping does not work with all containers. Most notably, swapping
+floating containers or containers that have a parent-child relationship to one
+another does not work.
+
+*Syntax*:
+----------------------------------------
+swap container with id|con_id|mark <arg>
+----------------------------------------
+
+*Examples*:
+-----------------------------------------------------------------
+# Swaps the focused container with the container marked »swapee«.
+swap container with mark swapee
+
+# Swaps container marked »A« and »B«
+[con_mark="^A$"] swap container with mark B
+-----------------------------------------------------------------

=== Sticky floating windows
If you want a window to stick to the glass, i.e., have it stay on screen even
=== Changing (named) workspaces/moving to workspaces
To change to a specific workspace, use the +workspace+ command, followed by the
-number or name of the workspace. To move containers to specific workspaces, use
-+move container to workspace+.
+number or name of the workspace. Pass the optional flag
++--no-auto-back-and-forth+ to disable <<back_and_forth>> for this specific call
+only.
+
+To move containers to specific workspaces, use +move container to workspace+.
You can also switch to the next and previous workspace with the commands
+workspace next+ and +workspace prev+, which is handy, for example, if you have
workspace using +move container to workspace back_and_forth+.
*Syntax*:
------------------------------------
+--------------------------------------------------------------------------------
workspace next|prev|next_on_output|prev_on_output
workspace back_and_forth
-workspace <name>
-workspace number <name>
+workspace [--no-auto-back-and-forth] <name>
+workspace [--no-auto-back-and-forth] number <name>
-move [window|container] [to] workspace <name>
-move [window|container] [to] workspace number <name>
+move [--no-auto-back-and-forth] [window|container] [to] workspace <name>
+move [--no-auto-back-and-forth] [window|container] [to] workspace number <name>
move [window|container] [to] workspace prev|next|current
------------------------------------
+--------------------------------------------------------------------------------
*Examples*:
-------------------------
bindsym $mod+r exec i3-input -F 'rename workspace to "%s"' -P 'New name: '
--------------------------------------------------------------------------
+If you want to rename workspaces on demand while keeping the navigation stable,
+you can use a setup like this:
+
+*Example*:
+-------------------------
+bindsym $mod+1 workspace number "1: www"
+bindsym $mod+2 workspace number "2: mail"
+...

+If a workspace does not exist, the command +workspace number "1: mail"+ will
+create workspace "1: mail".
+
+If a workspace with number 1 does already exist, the command will switch to this
+workspace and ignore the text part. So even when the workspace has been renamed
+to "1: web", the above command will still switch to it.

+=== Moving containers/workspaces to RandR outputs
To move a container to another RandR output (addressed by names like +LVDS1+ or
+VGA1+) or to a RandR output identified by a specific direction (like +left+,
+right+, +up+ or +down+), there are two commands:
*Syntax*:
-----------------------------------------------------
-move container to output left|right|down|up|<output>
-move workspace to output left|right|down|up|<output>
-----------------------------------------------------
+------------------------------------------------------------
+move container to output left|right|down|up|current|primary|<output>
+move workspace to output left|right|down|up|current|primary|<output>
+------------------------------------------------------------
*Examples*:
--------------------------------------------------------
# Put this window on the presentation output.
bindsym $mod+x move container to output VGA1
+
+# Put this window on the primary output.
+bindsym $mod+x move container to output primary
--------------------------------------------------------
+-------------------------------
+Note that you might not have a primary output configured yet. To do so, run:
+-------------------------
+xrandr --output <output> --primary

=== Moving containers/windows to marks
To move a container to another container with a specific mark (see <<vim_like_marks>>),

This feature is like the jump feature: It allows you to directly jump to a
specific window (this means switching to the appropriate workspace and setting

The additional +--toggle+ option will remove the mark if the window already has
-this mark, add it if the window has none or replace the current mark if it has
-another mark.
+this mark or add it otherwise. Note that you may need to use this in
+combination with +--add+ (see below) as any other marks will otherwise be
+removed.
-Refer to +show_marks+ if you don't want marks to be shown in the window decoration.
+By default, a window can only have one mark. You can use the +--add+ flag to
+put more than one mark on a window.
+
+Refer to <<show_marks>> if you don't want marks to be shown in the window decoration.
*Syntax*:

-mark [--toggle] <identifier>
+----------------------------------------------
+mark [--add|--replace] [--toggle] <identifier>
[con_mark="identifier"] focus
unmark <identifier>
-------------------------------

*Example (in a terminal)*:
-------------------------------
-$ i3-msg mark irssi
-$ i3-msg '[con_mark="irssi"] focus'
-$ i3-msg unmark irssi
-------------------------------
+---------------------------------------------------------
+# marks the focused container
+mark irssi
+
+# focus the container with the mark "irssi"
+'[con_mark="irssi"] focus'
+
+# remove the mark "irssi" from whichever container has it
+unmark irssi
+
+# remove all marks on all firefox windows
+[class="(?i)firefox"] unmark

=== Window title format
By default, i3 will simply print the X11 window title. Using +title_format+,
and the following placeholders which will be replaced:
+%title+::
- The X11 window title (_NET_WM_NAME or WM_NAME as fallback).
+ For normal windows, this is the X11 window title (_NET_WM_NAME or WM_NAME
+ as fallback). When used on containers without a window (e.g., a split
+ container inside a tabbed/stacked layout), this will be the tree
+ representation of the container (e.g., "H[xterm xterm]").
+%class+::
The X11 window class (second part of WM_CLASS). This corresponds to the
+class+ criterion, see <<command_criteria>>.
There is also +border toggle+ which will toggle the different border styles.
+Note that "pixel" refers to logical pixel. On HiDPI displays, a logical pixel
+may be represented by multiple physical pixels, so +pixel 1+ might not
+necessarily translate into a single pixel row wide border.
+
*Syntax*:

slides.
