<h2>Manipulating terminal groups<a class="headerlink" href="#manipulating-terminal-groups" title="Permalink to this headline"></a></h2>
<p>Grouping, as the name suggests, allows grouping of terminals allowing
actions to be taken that affect more than one terminal. As usual,
following along will help understanding, so lets start with a basic
window, then split into a 2x2 grid.</p>
<p>Let&#8217;s have another look at the grouping menu for reference, because
as we proceed, it will change:</p>
<img alt="_images/grouping_01.png" src="_images/grouping_01.png" />
<p>The first item <strong>New group...</strong> allows you to create a named group,
using an editable field that will appear next to the 3-box icon. By
default this will be given a randomly selected name from the names
of the Greek alphabet. Here you can see <strong>Phi</strong> was selected:</p>
<img alt="_images/grouping_02.png" src="_images/grouping_02.png" />
<p>You can either start typing to replace the provided one with something
more descriptive, or you can accept the default with <code class="docutils literal"><span class="pre">Return</span></code>. For
the purpose of this document I will just be using default names.</p>
<p>If you again click the 3-box/group button, you will see that several
new entries have been added to the menu:</p>
<img alt="_images/grouping_03.png" src="_images/grouping_03.png" />
<p>Because the terminal now has a group the first new entry is <strong>None</strong>
which will remove the grouping for this terminal.</p>
<p>Following that is a list of the known groups, in this case only <em>Phi</em>
so far. This list (plus the <em>None</em> entry) can be used to change the
group of this terminal.</p>
<p>Next are two items: <strong>Remove group Phi</strong> and <strong>Remove all groups</strong>.
You will only get the currently assigned group group as an option to
remove, as well as an option to remove all groups. This does not
close the group, but simply removes the group assignments from the
terminals.</p>
<p>The next option is more destructive: <strong>Close group Phi</strong> will exit
the terminals assigned to this group.</p>
<p>Here I&#8217;ve gone ahead and set the upper right terminal to the same
<em>Phi</em> group, and the lower left terminal to a <em>New group...</em> of
<strong>Epsilon</strong>.</p>
<img alt="_images/grouping_04.png" src="_images/grouping_04.png" />
<p>A quick glance at the menu again will show that the only change is
the addition of the <em>Epsilon</em> group to the list.</p>
<p>To change a group name you can either click on <em>New group...</em> again,
or <code class="docutils literal"><span class="pre">Shift</span></code>+<code class="docutils literal"><span class="pre">click</span></code> on the 3-box/group button, and the editable
field will reappear.</p>
<p>The current terminal is the one with focus. By clicking with key
modifiers on other terminals 3-box/group button we can speed up group
organisation. Here&#8217;s a list of mouse actions (including some already
detailed):</p>

<p>Skipping slightly ahead in the menu, there are two options that make

in which case new terminals have no group.</p>
<p>The second option <strong>Autoclean groups</strong> (default: on) will remove a
group from the menus group list when the last terminal with that

<div class="section" id="broadcasting-input-to-multiple-terminals">
<h2>Broadcasting input to multiple terminals<a class="headerlink" href="#broadcasting-input-to-multiple-terminals" title="Permalink to this headline"></a></h2>
<p>So first let me describe some terminology (no pun intended).
<strong>Broadcasting</strong> is the act of sending your input to multiple
terminals. The current terminal (the one with the red titlebar by
default) is always the <strong>broadcaster</strong>. Any terminal that is in
the same group as the current terminal is a potential <strong>receiver</strong>.
I say potential because the act of broadcasting can be turned on
and off independently of the grouping.</p>
<p>This can be an invaluable time-saver when having to do active
investigation across multiple machines where you would be repeating
the same commands on each of them.</p>
<p>Terminator&#8217;s titlebar is colour-coded to help you quickly see which
terminals are potential receivers, and whether they <em>will</em> receive
the broadcast input.</p>
<p>The titlebar is split into two parts. The leftmost part is the
3-box/group button that has one of three background colours as defined
in the <a class="reference internal" href="preferences.html#prefs-global"><span>Global</span></a> tab of <a class="reference internal" href="preferences.html#preferences"><span>Preferences Window</span></a>:</p>
<ul class="simple">
<li><em>Red</em> - The current terminal and broadcaster.</li>
<li><em>Blue</em> - A terminal that is in the same group as the broadcaster.</li>
<li><em>Grey</em> - A terminal in a different group, or no group.</li>
</ul>
<p>The second part consists of the title, and uses the same colouring
to show the following:</p>
<ul class="simple">
<li><em>Red</em> - The current terminal and broadcaster.</li>
<li><em>Blue</em> - A terminal that is acting as a receiver and will duplicate
input from the broadcaster.</li>
<li><em>Grey</em> - A terminal that is not a receiver.</li>
</ul>
<p>There are three settings for broadcasting, selected from the <em>Group
menu</em>. Following are an image of each of these modes, with <code class="docutils literal"><span class="pre">test</span></code>
typed into the current broadcasting terminal:</p>
<ul>
<li><p class="first"><em>Broadcast off</em></p>
<img alt="_images/broadcast_01.png" src="_images/broadcast_01.png" />
<p>Here you can see that only the current terminal receives input, even
though the upper right terminal is also a part of the <em>Phi</em> group.</p>
</li>
<li><p class="first"><em>Broadcast all</em></p>
<img alt="_images/broadcast_02.png" src="_images/broadcast_02.png" />
<p>Here you can see that all terminals, including those in other groups,
or with no group, receive the input.</p>
</li>
<li><p class="first"><em>Broadcast group</em> (default mode; can be changed in the

<p>Here you can see that only the terminal(s) in the same group in the
same group as the broadcaster receive input.</p>
</li>
</ul>
<p>Be careful with additional tabs, windows, or when you are zoomed or
maximised on a single terminal. Just because you cannot see a terminal
does not mean the terminal is not receiving. This can cause problems
if you are typing a destructive command without realising that this
command is going to other terminals.</p>
<p>Those with good eyesight may have spotted the other visual indicator
of the colours in the 3-box icon changing for the different status of
the terminals too. When you are zoomed or maximised, the presence of
blue in this icon might be the only visual indicator of receivers.</p>
<p>As with all things in Terminator, we have shortcuts to help you keep
your hands on the keyboard:</p>
<table border="1" class="docutils">
<colgroup>
<col width="47%" />
<col width="53%" />
</colgroup>
<thead valign="bottom">
<tr class="row-odd"><th class="head">Action</th>
<th class="head">Default Shortcut</th>
</tr>
</thead>
<tbody valign="top">
<tr class="row-even"><td>Broadcast off</td>
<td><code class="docutils literal"><span class="pre">Alt</span></code>+<code class="docutils literal"><span class="pre">O</span></code></td>
</tr>
<tr class="row-odd"><td>Broadcast all</td>
<td><code class="docutils literal"><span class="pre">Alt</span></code>+<code class="docutils literal"><span class="pre">A</span></code></td>

<tr class="row-even"><td>Broadcast group</td>
<td><code class="docutils literal"><span class="pre">Alt</span></code>+<code class="docutils literal"><span class="pre">G</span></code></td>

<div class="admonition warning">
<p class="first admonition-title">Warning</p>
<p>It has become apparent that IBus causes problems with
broadcast input. When multiple keystrokes are used to
<em>compose</em> a letter, such as the <code class="docutils literal"><span class="pre">AltGr</span></code>+<code class="docutils literal"><span class="pre">[</span></code>
followed by <code class="docutils literal"><span class="pre">a</span></code>, <code class="docutils literal"><span class="pre">o</span></code>, <code class="docutils literal"><span class="pre">u</span></code> keys to get <strong>ä</strong>,
<strong>ö</strong>, <strong>ü</strong> characters for the German language.</p>
<p>Instead of getting your composed letter in all receivers,
you will only get the composed letter in the current
terminal. If you copy and paste the character into the
current terminal then it will be input into the
receivers.</p>
<p class="last">You may not even realise that you are running IBus.
Killing it will temporarily fix the problem. There is
a fix for IBus and VTE, but only in the newer builds of
VTE. For that we would need the experimental GTK3
version of Terminator.</p>

<p>The last two menu items are slightly out of place here. They are the
same function as the shortcuts mentioned <a class="reference internal" href="gettingstarted.html#insert-termnum-shortcut"><span>here</span></a>.
They were added early on when the broadcast feature was added, and
the argument could be made for removing them. So far no-one has
though, so for now they will stay here.</p>
