== NAME
|
||
|
||
i3 - an improved dynamic, tiling window manager
|
||
|
||
== SYNOPSIS
|
||
|
||
i3 [-c configfile]
|
||
|
||
== DESCRIPTION
|
||
|
||
=== INTRODUCTION
|
||
|
||
i3 was created because wmii, our favorite window manager at the time, didn’t
|
||
provide some features we wanted (Xinerama done right, for example), had some
|
||
bugs, didn’t progress since quite some time and wasn’t easy to hack at all
|
||
(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.
|
||
|
||
=== TERMINOLOGY
|
||
|
||
Client::
|
||
A client is X11-speak for a window.
|
||
|
||
Table::
|
||
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.
|
||
+
|
||
By "snapping" a client in a specific direction, you increase its colspan/rowspan.
|
||
|
||
Container::
|
||
A container contains a variable number of clients. Each cell of the table is a container.
|
||
+
|
||
Containers can be used in various modes. The default mode is called "default" and just
|
||
resizes each client equally so that it fits.
|
||
|
||
Workspace::
|
||
A workspace is a set of clients (technically speaking, it’s just a table). Other window
|
||
managers call this "Virtual Desktops".
|
||
+
|
||
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), it’ll be assigned the screen you are currently
|
||
on.
|
||
|
||
Virtual Screen::
|
||
Using Xinerama, 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).
|
||
+
|
||
A virtual screen is the result of your Xinerama setup. For example, if you have attached
|
||
two real monitors (let’s say your laptop screen and a video projector) and enabled cloning, i3
|
||
will use one virtual screen with the size of the smallest screen you have attached (so
|
||
that you can see all your windows on each screen all the time).
|
||
If you have two monitors attached, one configured to be left of the other, i3 will use
|
||
two virtual screens.
|
||
|
||
== KEYBINDINGS
|
||
|
||
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).
|
||
|
||
Mod1+<direction>::
|
||
Focus window in <direction>.
|
||
|
||
Mod3+<direction>::
|
||
Focus container in <direction>.
|
||
|
||
Mod1+Shift+<direction>::
|
||
Move window to <direction>.
|
||
|
||
Mod3+Shift+<direction>::
|
||
Move container to <direction>.
|
||
|
||
Mod1+Control+<direction>::
|
||
Snap container to <direction>.
|
||
|
||
Mod1+<number>::
|
||
Switch to workspace <number>.
|
||
|
||
Mod1+Shift+<number>::
|
||
Move window to workspace <number>.
|
||
|
||
Mod1+f::
|
||
Toggle fullscreen mode.
|
||
|
||
Mod1+h::
|
||
Enable stacking layout for the current container.
|
||
|
||
Mod1+e::
|
||
Enable default layout for the current container.
|
||
|
||
Mod1+Shift+q::
|
||
Kills the current client.
|
||
|
||
Mod1+Shift+r::
|
||
Restarts i3 in place (without losing any windows, but the layout).
|
||
|
||
Mod1+Shift+e::
|
||
Exits i3.
|
||
|
||
== FILES
|
||
|
||
=== ~/.i3/config
|
||
|
||
When starting, i3 looks for ~/.i3/config and loads the configuration. If ~/.i3/config is not found,
|
||
i3 tries /etc/i3/config. You can specify a custom path using the -c option.
|
||
|
||
At the moment, you can specify only the path to your favorite terminal emulator, the font and keybindings.
|
||
|
||
At the moment, you have to bind to keycodes (find them out via xev(1)).
|
||
|
||
