<section id="page_navigation">
<title>Page Navigation</title>
<p>
The <gui>Page Navigation</gui> group of controls make it possible for you
to customize how <app>Orca</app> presents, and allow you to interact with,
text and other content.
</p>
<section id="page_navigation_control_caret">
<title>Control caret navigation</title>
<p>
This checkbox toggles <app>Orca</app>'s caret navigation on and off.
When it is on, <app>Orca</app> takes control of the caret as you arrow
around within a page; when it is off, Gecko's native caret navigation is
active.
</p>
<p>
Default value: checked
</p>
<note style="tip">
<title>This setting can be toggled on the fly</title>
<p>
To toggle this setting on the fly without saving it, use
<keyseq><key>Orca Modifier</key><key>F12</key></keyseq>.
</p>
</note>
</section>
<section id="page_navigation_focus_caret">
<title>Automatic focus mode during caret navigation</title>
<p>
If this checkbox is checked, <app>Orca</app> will automatically turn on
focus mode when you use caret navigation commands to navigate to a form
field. For example, pressing <key>Down</key> would allow you to move
into an entry but once you had done so, Orca would switch to focus mode
and subsequent presses of <key>Down</key> would be controlled by the web
browser and not by Orca. If this checkbox is not checked, <app>Orca</app>
would continue to control what happens when you press <key>Down</key>,
thus making it possible to arrow out of the entry and continue reading.
</p>
<p>
Default value: not checked
</p>
<note style="tip">
<title>Manually switching between browse mode and focus mode</title>
<p>
In order to start or stop interacting with the focused form field,
use <keyseq><key>Orca Modifier</key><key>A</key></keyseq> to switch
between browse mode and focus mode.
</p>
</note>
</section>
<section id="page_navigation_structural">
<title>Enable structural navigation</title>
<p>
This checkbox toggles <app>Orca</app>'s
<link xref="howto_structural_navigation">Structural Navigation</link>
on and off. Structural Navigation allows you to navigate by elements
such as headings, links, and form fields.
</p>
<p>
Default value: checked
</p>
<note style="tip">
<title>This setting can be toggled on the fly</title>
<p>
To toggle this setting on the fly without saving it, use
<keyseq><key>Orca Modifier</key><key>Z</key></keyseq>.
</p>
</note>
</section>
<section id="page_navigation_focus_structural">
<title>Automatic focus mode during structural navigation</title>
<p>
If this checkbox is checked, <app>Orca</app> will automatically turn on
focus mode when you use structural navigation commands to navigate to a
form field. For example, pressing <key>E</key> to move to the next entry
would move focus there and also turn focus mode on so that your next press
of <key>E</key> would type an "e" into that entry. If this checkbox is not
checked, then <app>Orca</app> will leave you in browse mode and your next
press of <key>E</key> would move you to the next entry on the page.
</p>
<p>
Default value: not checked
</p>
<note style="tip">
<title>Manually switching between browse mode and focus mode</title>
<p>
In order to start or stop interacting with the focused form field,
use <keyseq><key>Orca Modifier</key><key>A</key></keyseq> to switch
between browse mode and focus mode.

</section>
<section id="page_navigation_speak">
<title>Automatically start speaking a page when it is first loaded</title>
<p>
If this checkbox is checked, <app>Orca</app> will perform a Say All on
the newly opened web page or email.
</p>
<p>
Default value: checked for Firefox; not checked for Thunderbird
</p>
</section>
<section id="page_navigation_summary">
<title>Present summary of a page when it is first loaded</title>
<p>
If this checkbox is checked, <app>Orca</app> will summarize details about the
newly opened web page or email, such as the number of headings, landmarks,
and links.
</p>
<p>
Default value: checked for Firefox; not checked for Thunderbird
</p>
</section>
<section id="page_navigation_layout_mode">
<title>Enable layout mode for content</title>
<p>
If this checkbox is checked, <app>Orca</app>'s caret navigation will respect
the on-screen layout of the content and present the full line, including any
links or form fields on that line. If this checkbox is not checked, <app>Orca</app>
will treat objects such as links and form fields as if they were on separate
lines, both for presentation and navigation.
</p>
<p>
Default value: checked
</p>
</section>
</section>
<section id="table_options">
<title>Table Options</title>

<section id="find_options">
<title>Find Options</title>
<p>
The <gui>Find Options</gui> group of controls make it possible for you to
customize how <app>Orca</app> presents the results of a search conducted
using the application's built-in search functionality.
</p>
<section id="find_options_speak_during_find">
<title>Speak results during find</title>
<p>
If this checkbox is checked, <app>Orca</app> will read the line which
matches your current search query.
</p>
<p>
Default value: checked
</p>
</section>
<section id="find_options_speak_changed_lines_during_find">
<title>Only speak changed lines during find</title>
<p>
If this checkbox is checked, <app>Orca</app> will not present the
matching line if it is the same line as the previous match. This
option is designed to prevent "chattiness" on a line with multiple
instances of the string for which you are searching.
</p>
<p>
Default value: not checked
</p>
</section>
<section id="find_options_minimum_match_length">
<title>Minimum length of matched text</title>
<p>
This editable spin button is where you can specify the number of
characters which must match before <app>Orca</app> announces the
matching line. This option is also designed to prevent "chattiness"
as there are many matches when you first begin typing the string
for which you are searching.
</p>
<p>
Default value: 4
