[orca-list] How can possible enabling Evince the caret navigation?

[Hammer Attila <hammera pickup hu>]

Hi List,

I tryed reading a PDF document with Evince 3.10.3 my Ubuntu 14.04 
development system.
With Evince application I not see any menu items to goto the preferences 
dialog, in GNOME Shell applications menu not have too a preferences menu 
item for Evince.
How can possible enabling the caret navigation support for Evince when I 
reading a pdf document?

I already tryed F7, SHIFT+F7, ALT+F7, CTRL+F7 keystrokes without good luck.
I using GNOME Shell 3.10.3, Evince 3.10.3 and Orca master branch version.

Anybody have an ydea?
Testcase:
1. Open a text containing pdf document.
2. Try enabling the caret navigation in Evince, and try reading document 
frame content with arrow keys.
Expected result: If the caret navigation support have possibility to 
enable, Orca reading actual line content.
Actual result: nothing happening when I using arrow keys, with braille 
scrolling I see only the actual page content.
Note: if I using up or down buttons in Evince to switch between page 
content, Orca sayall the actual page content.

An example pdf document link with I experienced this issue:
