With Opera you can do the following things:

1. Select a high contrast style sheet from the View/Style menu to see
what changes to high contrast. All text should be in high contrast.

2. If you change the window size does the content wrap to the new
window size so that the user does not need to horizontally scroll.

3. As you change font size (- and + key on numeric keypad) does text
reflow to the change in font sizes

4. Do links make sense in isolation. Use Control+J to bring up a
list of just link text.

5. Is there proper use of headers, Use the W and S keys to navigate
the headers of the document. it should move focus to the major
topics or areas of the web resource.

6. Select the ignore tables style option in View/Styles menu to see
if the document makes sense linearized. This is important for screen
reader compatibility and also from people with learning disabilities
to simplify the layout of the document.

7. have you uses any images to style text. These should be changed
to text and sylized with CSS.

8. Turn off images (G key) to test if ALT text is present for images.
Note: ALT for AREA element is not rendered by any major browser, so
should be considered and inaccessible technique, unless there are
redundant text links in the document.

9. Test ACCESSKEY bindings (Press ESCape key and then press ACCESSKEY)

The beauty of Opera is that all these things can be done in one or
two keystrokes or mouse clicks. making it easily to go between the
authors preferred styling and styling a user needs. These types of
tests really strain pages that use out of date graphical design
techniques for styling content and therefore leads to designs that
are better for everyone.
