Panel "Preview"

What it does

In the panel "Preview" you get a screenreader preview of your document after clicking the button "Refresh".

Use it for

  • checking the document structure visually (logical order, semantics)
  • checking the correct presentation of text (spaces, characters)

How to use it

  1. Simply click the button "Preview" at the bottom left corner of the screen
  2. Click the button "Refresh"
  3. Scroll down to check the complete content and the structure element. Move the cursor on a structure element symbol, then the name of the structure element will be displayed. Or have a look on our table with an explanation of all symbols.
