Google Toolbar v5 for Internet Explorer added few more features and releases adds support for Windows Accessibility APIs (used by screen readers, etc.) and enables keyboard navigation and access. From inside a browser with Toolbar installed, the global shortcut Alt+G places your cursor in the Google Toolbar search box. If you're using a screen reader, you'll hear "Google Toolbar Search". Pressing the Tab key brings keyboard focus to the button placed immediately after the search box, and right and left arrow keys move focus between buttons. More information on keyboard access is documented in the Toolbar Help Center (query 'accessibility').
