 <p>You can't and you shouldn't. Different verbosity settings like functional keys announcement, punctuation reading, repeated characters announcement, treatment of dialog controls and so on, and so forth, — all of these are entirely up to the screen reader and the user who adjusts these settings. Just like, for example, speech rate or pitch. As a JAWS user, I wouldn't be happy, and more than that, I would be angry if some app developer forced me to turn off my <code>Tab</code> announcement or changed my punctuation level.</p> <p><strong>Update</strong>: If you just want to turn off keystrokes announcement for yourself, do the following:</p> <ol> <li>Press <em>Insert+6</em> on the number row to go to JAWS Settings Center. You can do this from the JAWS main menu, but the single keystroke is much faster.</li> <li>If you want to make your change by default for all apps, press <em>Ctrl+Shift+D</em> to open the default file.</li> <li>In the search box type <code>labels</code> and search for Key Labels.</li> <li>In the dialog that appears turn off the announcement for all of the keystrokes you don't want to hear. Note that if you mute <em>Tab</em>, all of the keystrokes like <em>Shift+Tab</em> and <em>Ctrl+Tab</em> will be muted automagically.</li> <li>click OK several times to leave Settings Center and save your settings.</li> </ol>
