Hyperlinks are hidden links on a web page that allow you to navigate around the place.  When you click on a hyperlink, your browser will open the page associated with the link.  Normally they will be a different colour from the surrounding text and may be underlined.  That is the way I have done them on these pages.  To go back to the main page where you were just now, you can click on the "Back" button on the main toolbar at the top of the page (it has a big left facing arrow on it). Try it now and then either click on the forward button which is a big arrow facing to the right or click on the same link that you clicked on originally to come to this page.  Whenever your mouse pointer changes from an arrow to a pointing hand, you are over a hyperlink and can click it and go to the linked page.
