When input's have access keys, and connected <label> elements, the updateTooltipAccessKeys() function should also update the title of the label element.
Fon instance on Edit pages:
<input name="wpWatchthis" type="checkbox" value="1" tabindex="4" accesskey="w" id="wpWatchthis" class="webfonts-changed">
<label for="wpWatchthis" id="mw-editpage-watch" title="Add this page to your watchlist [w]">Watch this page</label>
