Notifications</title> 6 <desc>Reading previously-received messages</desc> 7 <credit type="author"> 8 <name>Joanmarie Diggs</name> 9 <email>joanied@gnome.org</email> 10 </credit> 11 <license> 12 <p>Creative Commons Share Alike 3.0</p> 13 </license> 14 </info> 15 <title>Notifications</title> 16 <p> 17 The GNOME Desktop includes a "notification area" which can be used by 18 applications to present information to the user. Examples of notifications 19 include incoming chat messages, the details associated with the song your 20 media player is starting to play, and warnings that your battery level is 21 getting low. 22 </p> 23 <p> 24 Because notifications are intended to present information to users without 25 interrupting what the user is doing, these messages tend to appear and 26 disappear relatively quickly. They are also not focusable. While 27 <app>Orca</app> will present these messages to you as they come in, it is 28 far too easy to interrupt <app>Orca</app>'s announcement accidentally by 29 continuing to type or to change focus. For this reason, <app>Orca</app> has 30 three commands which you can use to access previously-displayed notification 31 messages: 32 </p> 33 <list> 34 <item> 35 <p>Present the last (most recent) notification message</p> 36 </item> 37 <item> 38 <p>Present the previous notification message</p> 39 </item> 40 <item> 41 <p>Present list of all notification messages</p> 42 </item> 43 </list> 44 <p> 45 The first two commands are designed mainly for quick access to a message 46 you just received. The last command is the most powerful as it stores your 47 notification message history. 48 </p> 49 <p> 50 When you enter the list of notification messages, you will be told the size 51 of the list and prompted with the following choices: 52 </p> 53 <list> 54 <item><p>Press H for help.</p></item> 55 <item><p>Use Up, Down, Home or End to navigate in the list.</p></item> 56 <item><p>Press Escape to exit.</p></item> 57 <item><p>Press Space to repeat the last message read.</p></item> 58 <item><p>Press one digit to read a specific message.</p></item> 59 </list> 60 <p> 61 Note that the most recently-received message is at the top of the list. 62 </p> 63 <p> 64 Each of <app>Orca</app>'s notification review commands is unbound by 65 default. You can bind any or all of them to the shortcut or shortcuts 66 you choose. How to do so is described in the 67 <link xref="howto_key_bindings">Introduction to Key Bindings</link>. 68 </p> 69</page> 70
