Use of Quick Access Keys
I’ve implemented these to allow users of browsers which recognise them to navigate more quickly in certain areas of the site. 

Microsoft Internet Explorer uses Alt+ the access key followed by Enter

Firefox 2.0 uses Shift+Alt as the keystroke combination to invoke access keys.

In Opera, access keys are activated by simultaneously pressing the Shift and Esc. A list of available access keys are then displayed, so just press the relevant key.

In the index of countries, pressing G moves the listing to the countries with names beginning with "G".  The same applies to all other letters, except X which is used for "New on the Web". These keys also work on the home page.

In the species pages and country pages, the following are implemented :-
 

Previous page P
Index I
Home H
Next page N

With MSIE4, pressing [ALT] with the key passes control immediately, but with MSIE5, you have to press [Enter].

Back to the home page.
