== DESCRIPTION
=== INTRODUCTION
2009-02-25 01:18:07 +01:00
i3 was created because wmii, our favorite window manager at the time, didnt
2010-03-15 22:41:39 +01:00
provide some features we wanted (multi-monitor done right, for example), had
some bugs, didnt progress since quite some time and wasnt easy to hack at all
2009-02-25 01:18:07 +01:00
(source code comments/documentation completely lacking). Still, we think the
wmii developers and contributors did a great job. Thank you for inspiring us to
create i3.
Please be aware that i3 is primarily targeted at advanced users and developers.

=== IMPORTANT NOTE TO nVidia BINARY DRIVER USERS
If you are using the nVidia binary graphics driver (also known as 'blob')
you need to use the +--force-xinerama+ flag (in your .xsession) when starting
i3, like so:
----------------------------------------------
exec i3 --force-xinerama -V >>~/.i3/i3log 2>&1
----------------------------------------------
See also docs/multi-monitor for the full explanation.

=== TERMINOLOGY
Client::
A client is X11-speak for a window.
Table::
2010-03-15 22:41:39 +01:00
Your workspace is managed using a table. You can move windows around and create
new columns (move a client to the right) or rows (move it to the bottom)
implicitly.
2009-02-15 18:51:19 +01:00
+
By "snapping" a client in a specific direction, you increase its colspan/rowspan.
Container::
2010-03-15 22:41:39 +01:00
A container contains a variable number of clients. Each cell of the table is a
container.
2009-02-15 18:51:19 +01:00
+
2010-03-15 22:41:39 +01:00
Containers can be used in various modes. The default mode is called "default"
and just resizes each client equally so that it fits.
2009-02-15 18:51:19 +01:00
Workspace::
2010-03-15 22:41:39 +01:00
A workspace is a set of clients (technically speaking, its just a table).
Other window managers call this "Virtual Desktops".
2009-02-15 18:51:19 +01:00
+
2010-03-15 22:41:39 +01:00
In i3, each workspace is assigned to a specific virtual screen. By default,
screen 1 has workspace 1, screen 2 has workspace 2 and so on… However, when you
create a new workspace (by simply switching to it), itll be assigned the
screen you are currently on.
Output::
Using XRandR, you can have an X11 screen spanning multiple real monitors.
Furthermore, you can set them up in cloning mode or with positions (monitor 1
is left of monitor 2).
2009-02-15 18:51:19 +01:00
+
2010-03-15 22:41:39 +01:00
i3 uses the RandR API to query which outputs are available and which screens
are connected to these outputs.

== KEYBINDINGS
2009-02-25 01:18:07 +01:00
Here is a short overview of the default keybindings:
j/k/l/;::
Direction keys (left, down, up, right). They are on your homerow (see the mark
on your "j" key). Alternatively, you can use the cursor keys.
2009-02-15 18:51:19 +01:00
Mod1+<direction>::
Focus window in <direction>.
Mod3+<direction>::
Focus container in <direction>.
2009-02-15 18:51:19 +01:00
Mod1+Shift+<direction>::
Move window to <direction>.
Mod3+Shift+<direction>::
Move container to <direction>.
2009-02-25 01:18:07 +01:00
Mod1+Control+<direction>::
Snap container to <direction>.
2009-02-15 18:51:19 +01:00
Mod1+<number>::
Switch to workspace <number>.
Mod1+Shift+<number>::
Move window to workspace <number>.
2009-02-25 01:18:07 +01:00
Mod1+f::
Toggle fullscreen mode.
2009-05-03 16:52:53 +02:00
Mod1+h::
2009-02-25 01:18:07 +01:00
Enable stacking layout for the current container.
2009-05-03 16:52:53 +02:00
Mod1+e::
2009-02-25 01:18:07 +01:00
Enable default layout for the current container.
Mod1+Shift+Space::
Toggle tiling/floating for the current window.
Mod1+t::
Select the first tiling window if the current window is floating and vice-versa.
Mod1+Shift+q::
2010-03-15 22:41:39 +01:00
Kills the current window. This is equivalent to "clicking on the close button",
meaning a polite request to the application to close this window. For example,
Firefox will save its session upon such a request. If the application does not
support that, the window will be killed and it depends on the application what
happens.
Mod1+Shift+r::
Restarts i3 in place (without losing any windows, but at this time, the layout
and placement of windows is not retained).
Mod1+Shift+e::
Exits i3.

== FILES
2010-03-15 22:41:39 +01:00
=== \~/.i3/config (or ~/.config/i3/config)
2009-02-25 01:18:07 +01:00
2010-03-15 22:41:39 +01:00
When starting, i3 looks for configuration files in the following order:
1. ~/.config/i3/config (or $XDG_CONFIG_HOME/i3/config if set)
2. /etc/xdg/i3/config (or $XDG_CONFIG_DIRS/i3/config if set)
3. ~/.i3/config
4. /etc/i3/config
2009-02-25 01:18:07 +01:00
2010-03-15 22:41:39 +01:00
You can specify a custom path using the -c option.

== ENVIRONMENT
=== I3SOCK
If no ipc-socket is specified in the configfile, this variable is used
to determine the path, at wich the unix domain socket is created, on which
i3 listenes to incoming connections.
2009-02-15 18:51:19 +01:00
== TODO
There is still lot of work to do. Please check our bugtracker for up-to-date
information about tasks which are still not finished.
2009-02-15 18:51:19 +01:00
== SEE ALSO
You should have a copy of the userguide (featuring nice screenshots/graphics
which is why this is not integrated into this manpage), the debugging guide,
and the "how to hack" guide. If you are building from source, run:
+make -C docs+
