<title>What is a notification?</title>
25
<p>If an application or a system component wants to get your attention, a
26
notification will be shown at the bottom of the screen.</p>
27
<p>For example, if you get a new chat message, plug in an external device
28
(like a USB stick), new updates are available for your computer, or your
29
computer’s battery is low, you will get a notification informing you.</p>
30
<p>To minimize distraction, some notifications first appear as a single
31
line. You can move your mouse over them to see their full content.</p>
33

35
<p>Other notifications have selectable option buttons. To close one of these
36
notifications without selecting one of its options, click anywhere on the

<title>The message tray</title>
46
<p>The message tray gives you a way to get back to your notifications when it
47
is convenient for you. It appears when you move your mouse to the bottom right
48
corner of the screen, and contains all the notifications that you have not
49
acted upon or that permanently reside in it.</p>
50
<p>You can view the notifications by clicking on the message tray items. These
51
are usually messages sent by applications. However, chat notifications are
52
given special treatment, and are represented by the individual contacts who sent
53
you the chat messages.</p>
54
<p>The message tray is always visible in the activities overview.</p>

<p>If you're working on something and don't want to be bothered, you can
67
switch off notifications. Just click your name on the top bar and change the
68
<gui>Notifications</gui> toggle to <gui>OFF</gui>.</p>
70
<p>When switched off, most notifications will not pop up at the bottom of the
71
screen. Very important notifications, such as when your battery is critically
72
low, will still pop up. Notifications will still be available in the messaging
73
tray when you move your mouse to the bottom right corner, and they will be
74
shown to you when you switch the toggle to <gui>ON</gui> again.</p>
