I'm going to substitute the angle brackets with  for this post.
[a href="#id"]This will be the link you click[/a]
Remember you need the # sign to make it an anchor link or else when you click the link you'll find a page not found message or something waiting for you.
[div id="id"]The text the link will direct to[/div]
That's the anchor your link will point to.
Also, if you've already made something like a header or paragraph, you can do something like this: [h2 id="id"]The text the link will direct to[/h2].
The ID attribute works for most elements.
And just for future reference: HTML Dog is a very simple reference guide for CSS/HTML. W3C is okay but I thought HTML Dog was more helpful. ;)
