Gecko Navigation PreferencesPage Navigation
The Page Navigation group of controls make it possible for you
to customize how Orca presents, and allow you to interact with,
text and other content.
Use Orca Caret Navigation
This checkbox toggles Orca's caret navigation on and off.
When it is on, Orca takes control of the caret as you arrow
around within a page; when it is off, Gecko's native caret navigation is
active.
Default value: checked
This setting can be toggled on the fly
To toggle this setting on the fly without saving it, use
Orca ModifierF12.
Use Orca Structural Navigation
This checkbox toggles Orca's
Structural Navigation
on and off. Structural Navigation allows you to navigate by elements
such as headings, links, and form fields.
Default value: checked
This setting can be toggled on the fly
To toggle this setting on the fly without saving it, use
Orca ModifierZ.
Grab focus on objects when navigating
If this checkbox is checked, Orca will perform an explicit
focus grab as you navigate using the Orca-controlled caret.
Doing this was necessary in older versions of Firefox and
Thunderbird.
Default value: not checked
Position cursor at start of line when navigating vertically
If this checkbox is checked, Orca will always move the caret
to the beginning of the line when Orca is controlling the
caret and you press Up or Down Arrow to read the previous or next line.
If this checkbox is not checked, Orca will attempt to keep
the caret in the same horizontal position as you navigate Up or Down.
Default value: not checked
Find Options
The Find Options group of controls make it possible for you to
customize how Orca presents the results of a search conducted
using the application's built-in search functionality.
Speak results during find
If this checkbox is checked, Orca will read the line which
matches your current search query.
Default value: checked
Only speak changed lines during find
If this checkbox is checked, Orca 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.
Default value: not checked
Minimum length of matched text
This editable spin button is where you can specify the number of
characters which much match before Orca announces the
matching line. This option is also designed to prevent "chattiness"
as there are many matches when you first begin typing string for
which you are searching.
