Bookworm supports reading the content of the document using an installed text-to-speech voice. Just press F5 to start the speech, F6 to pause or resume, and F7 to stop the speech.
During reading aloud, you can skip backward or foreword by paragraph by pressing Alt plus the left and right arrow keys.
Reading with Screen Readers
In addition to Bookworm’s built-in text-to-speech features, you can take advantage of your screen reader’s continuous reading functionality (also known as “say all”). Bookworm provides support for this functionality through its “continuous reading mode”. This mode is active by default, and you can disable it from the reading page of the application preferences. While the continuous reading mode is active, pages are turned automatically as the screen reader progresses through the document.
Viewing A Fully Rendered Version of The Current Page
When a document is open, press Ctrl + R or click on “Render Page” in the “Tools” menu. The document is now displayed with text formatting and images if present in the document. Press the escape key to dismiss this view and return to the default textual view.
In the Render View you can use Ctrl + to zoom-in, Ctrl + – to zoom-out and Ctrl + 0 to reset the zoom level
You can use the document navigation commands, mentioned above, to navigate the render view as well.
