I run Ubuntu 18.04 and have installed version 3.28.0 of the Orca screenreader with sudo apt-get install gnome-orca.
When I start Orca and open a PDF document, it reads its file name out loud, and navigation moves inside the document (such as the items of the context menu when I click right on the PDF page). However, I cannot get it to read the contents of the page until the end of the chosen page. Instead, when I highlight text with a left click, it reads just this text - twice, once when highlighted and again when un-highlighted.
How can I get it to read a whole page (once)?
