72 configured modifier. This is the alt key (Mod1) by default, with windows (Mod4)
\r
73 being a popular alternative.</p></div>
\r
75 <h3 id="_opening_terminals_and_moving_around">2.1. Opening terminals and moving around</h3>
\r
76 <div class="paragraph"><p>One very basic operation is opening a new terminal. By default, the keybinding
\r
77 for this is mod+Enter, that is Alt+Enter in the default configuration. By
\r
78 pressing mod+Enter, a new terminal will be opened. It will fill the whole

79 space available on your screen.</p></div>

\r
83 <div class="paragraph"><p>If you now open another terminal, i3 will place it next to the current one,
\r
84 splitting the screen size in half. Depending on your monitor, i3 will put the
\r
85 created window beside the existing window (on wide displays) or below the
\r
86 existing window (rotated displays).</p></div>

88 <img src="two_terminals.png" alt="Two terminals" />
\r
90 <div class="paragraph"><p>To move the focus between the two terminals, you can use the direction keys
\r
91 which you may know from the editor <tt>vi</tt>. However, in i3, your homerow is used
\r
92 for these keys (in <tt>vi</tt>, the keys are shifted to the left by one for
\r
93 compatibility with most keyboard layouts). Therefore, <tt>mod+J</tt> is left, <tt>mod+K</tt>
\r
94 is down, <tt>mod+L</tt> is up and <tt>mod+;</tt> is right. So, to switch between the
\r
95 terminals, use <tt>mod+K</tt> or <tt>mod+L</tt>. Of course, you can also use the arrow keys.</p></div>
\r
96 <div class="paragraph"><p>At the moment, your workspace is split (it contains two terminals) in a
\r
97 specific direction (horizontal by default). Every window can be split
\r
98 horizontally or vertically again, just like the workspace. The terminology is
\r
99 "window" for a container that actually contains an X11 window (like a terminal
\r
100 or browser) and "split container" for containers that consist of one or more

\r
115 Windows are sized so that every window gets an equal amount of space in the

\r
133 The same principle as <tt>stacking</tt>, but the list of windows at the top is only

134 a single line which is vertically split.

\r
152 <h3 id="_opening_other_applications">2.4. Opening other applications</h3>
\r
153 <div class="paragraph"><p>Aside from opening applications from a terminal, you can also use the handy
\r
154 <tt>dmenu</tt> which is opened by pressing <tt>mod+d</tt> by default. Just type the name
\r
155 (or a part of it) of the application which you want to open. The corresponding
\r
156 application has to be in your <tt>$PATH</tt> for this to work.</p></div>
\r
157 <div class="paragraph"><p>Additionally, if you have applications you open very frequently, you can
\r
158 create a keybinding for starting the application directly. See the section

\r
163 <div class="paragraph"><p>If an application does not provide a mechanism for closing (most applications
\r
164 provide a menu, the escape key or a shortcut like <tt>Control+W</tt> to close), you
\r
165 can press <tt>mod+Shift+q</tt> to kill a window. For applications which support
\r
166 the WM_DELETE protocol, this will correctly close the application (saving
\r
167 any modifications or doing other cleanup). If the application doesn’t support
\r
168 the WM_DELETE protocol your X server will kill the window and the behaviour
\r
169 depends on the application.</p></div>

171 <div class="sect2">
\r
172 <h3 id="_using_workspaces">2.6. Using workspaces</h3>
\r
173 <div class="paragraph"><p>Workspaces are an easy way to group a set of windows. By default, you are on
\r
174 the first workspace, as the bar on the bottom left indicates. To switch to
\r
175 another workspace, press <tt>mod+num</tt> where <tt>num</tt> is the number of the workspace
\r
176 you want to use. If the workspace does not exist yet, it will be created.</p></div>
\r
177 <div class="paragraph"><p>A common paradigm is to put the web browser on one workspace, communication
\r
178 applications (<tt>mutt</tt>, <tt>irssi</tt>, …) on another one, and the ones with which you
\r
179 work, on the third one. Of course, there is no need to follow this approach.</p></div>
\r
180 <div class="paragraph"><p>If you have multiple screens, a workspace will be created on each screen at
\r
181 startup. If you open a new workspace, it will be bound to the screen you
\r
182 created it on. When you switch to a workspace on another screen, i3 will set
\r
183 focus to that screen.</p></div>

\r
187 <div class="paragraph"><p>To move a window to another workspace, simply press <tt>mod+Shift+num</tt> where
\r
188 <tt>num</tt> is (like when switching workspaces) the number of the target workspace.
\r
189 Similarly to switching workspaces, the target workspace will be created if
\r
190 it does not yet exist.</p></div>

202 to upgrade to a newer version of i3) you can use <tt>mod+Shift+r</tt>.</p></div>

\r
209 <h3 id="_floating">2.11. Floating</h3>
\r
210 <div class="paragraph"><p>Floating mode is the opposite of tiling mode. The position and size of a window
\r
211 are not managed by i3, but by you. Using this mode violates the tiling
\r
212 paradigm but can be useful for some corner cases like "Save as" dialog
\r
213 windows, or toolbar windows (GIMP or similar). Those windows usually set the
\r
214 appropriate hint and are opened in floating mode by default.</p></div>
\r
215 <div class="paragraph"><p>You can enable floating mode for a window by pressing <tt>mod+Shift+Space</tt>. By
\r
216 dragging the window’s titlebar with your mouse you can move the window
\r
217 around. By grabbing the borders and moving them you can resize the window. You
\r
218 can also do that by using the <a href="#floating_modifier">[floating_modifier]</a>.</p></div>
\r
219 <div class="paragraph"><p>For resizing floating windows with your keyboard, see <a href="#resizingconfig">[resizingconfig]</a>.</p></div>

226 <div class="sectionbody">
\r
227 <div class="paragraph"><p>i3 stores all information about the X11 outputs, workspaces and layout of the
\r
228 windows on them in a tree. The root node is the X11 root window, followed by
\r
229 the X11 outputs, then dock areas and a content container, then workspaces and
\r
230 finally the windows themselve. In previous versions of i3 we had multiple lists
\r
231 (of outputs, workspaces) and a table for each workspace. That approach turned
\r
232 out to be complicated to use (snapping), understand and implement.</p></div>

234 <h3 id="_the_tree_consists_of_containers">3.1. The tree consists of Containers</h3>
\r
235 <div class="paragraph"><p>The building blocks of our tree are so called <tt>Containers</tt>. A <tt>Container</tt> can
\r
236 host a window (meaning an X11 window, one that you can actually see and use,
\r
237 like a browser). Alternatively, it could contain one or more <tt>Containers</tt>. A
\r
238 simple example is the workspace: When you start i3 with a single monitor, a
\r
239 single workspace and you open two terminal windows, you will end up with a tree
\r

254 <h3 id="_orientation_and_split_containers">3.2. Orientation and Split Containers</h3>
\r
255 <div class="paragraph" id="OrientationSplit"><p>It is only natural to use so-called <tt>Split Containers</tt> in order to build a
\r
256 layout when using a tree as data structure. In i3, every <tt>Container</tt> has an
\r
257 orientation (horizontal, vertical or unspecified). So, in our example with the
\r
258 workspace, the default orientation of the workspace <tt>Container</tt> is horizontal
\r
259 (most monitors are widescreen nowadays). If you change the orientation to
\r
260 vertical (<tt>mod+v</tt> in the default config) and <strong>then</strong> open two terminals, i3 will
\r
261 configure your windows like this:</p></div>

\r
268 <div class="paragraph"><p>An interesting new feature of the tree branch is the ability to split anything:
\r
269 Let’s assume you have two terminals on a workspace (with horizontal
\r
270 orientation), focus is on the right terminal. Now you want to open another
\r
271 terminal window below the current one. If you would just open a new terminal
\r
272 window, it would show up to the right due to the horizontal workspace
\r
273 orientation. Instead, press <tt>mod+v</tt> to create a <tt>Vertical Split Container</tt> (to
\r
274 open a <tt>Horizontal Split Container</tt>, use <tt>mod+h</tt>). Now you can open a new
\r
275 terminal and it will open below the current one:</p></div>

\r
296 <div class="paragraph"><p>So, how can you open a new terminal window to the <strong>right</strong> of the current one?
\r
297 The solution is to use <tt>focus parent</tt>, which will focus the <tt>Parent Container</tt> of
\r
298 the current <tt>Container</tt>. In this case, you would focus the <tt>Vertical Split
\r
299 Container</tt> which is <strong>inside</strong> the horizontally oriented workspace. Thus, now new

420 Unlike other window managers, i3 can use Mode_switch as a modifier. This allows
\r
421 you to remap capslock (for example) to Mode_switch and use it for both: typing
\r
422 umlauts or special characters <em>and</em> having some comfortably reachable key
\r
423 bindings. For example, when typing, capslock+1 or capslock+2 for switching
\r
424 workspaces is totally convenient. Try it :-).

432 or configure the so called floating modifier which you can then press and

433 click anywhere in the window itself to move it. The most common setup is to
\r
434 use the same key you use for managing windows (Mod1 for example). Then
\r
435 you can press Mod1, click into a window using your left mouse button, and drag
\r
436 it to the position you want.</p></div>

\r
553 the title change. As i3 will get the title as soon as the application maps the

555 to match on <em>Firefox</em> in this case.</p></div>

1032 <div class="sectionbody">
\r
1033 <div class="paragraph"><p>As you can see in the goal list on the website, i3 was specifically developed
\r
1034 with support for multiple monitors in mind. This section will explain how to
\r
1035 handle multiple monitors.</p></div>
\r
1036 <div class="paragraph"><p>When you have only one monitor, things are simple. You usually start with
\r
1037 workspace 1 on your monitor and open new ones as you need them.</p></div>
\r
1038 <div class="paragraph"><p>When you have more than one monitor, each monitor will get an initial
\r
1039 workspace. The first monitor gets 1, the second gets 2 and a possible third
\r
1040 would get 3. When you switch to a workspace on a different monitor, i3 will
\r
1041 switch to that monitor and then switch to the workspace. This way, you don’t
\r
1042 need shortcuts to switch to a specific monitor, and you don’t need to remember
\r
1043 where you put which workspace. New workspaces will be opened on the currently
\r
1044 active monitor. It is not possible to have a monitor without a workspace.</p></div>
\r
1045 <div class="paragraph"><p>The idea of making workspaces global is based on the observation that most
\r
1046 users have a very limited set of workspaces on their additional monitors.
\r
1047 They are often used for a specific task (browser, shell) or for monitoring
\r
1048 several things (mail, IRC, syslog, …). Thus, using one workspace on one monitor
\r
1049 and "the rest" on the other monitors often makes sense. However, as you can
\r
1050 create an unlimited number of workspaces in i3 and tie them to specific
\r
1051 screens, you can have the "traditional" approach of having X workspaces per
\r
1052 screen by changing your configuration (using modes, for example).</p></div>
