How do you make a link go down to a certain part, for example Java. How would it make it jump to the line where it says that? I understand how to link it, but I don't know how to make it jump to a line.

Chapter 1: {Java} (I want to make it so when you click the link it goes to this line)

tried it.. got no where fast.
<br> <b> and a few others will work but cannot get <a name= or <a href=  to work
(yep i put em inside html tags) 

the tooltip when you enable basic html says these will work:
<b>, <u>, <i>, <s>, <em>, <ins>, <del>
<a href="">
<img src="" alt="" />
<br />, <hr />
<pre>, <blockquote>

a href wont work for me
img src will

odd

If this doesn't work:
then maybe the custom BBC code could be used to make an 'a' tag.

Kalphite this will work, as Omikron posted it..   
Just remember you can use only html in between the [ html ] brackets. 
BBcode won't work inside them 

I'll try to explain those two sections of the code.

You will need to "name" each section that you want to go to when clicking on the choices at the top of the post.

Let's say you have a post that has 3 long sections in it.   The sections are about apples, bananas, and pears.    heh

Where your heading for that section in the post is do this:
<a name='bananas'>All About Bananas</a>

Do that for each place in the post that you are going to want to go "to"
For instance:

Banana Information  goes here


Apple Information goes here


Pears Information goes here


In the list at the TOP of the post  you would put this:
 

When they click on All About Bananas in the list it will take them to that spot in the post.
Same for Apples, and Pears.

Make sure everyting in between the  html tags  is html code.  bbcode will not work so you need to know html to do this.  Everything has to be inside the [ html ]  and [ /html ] tags

There is a Guide here that shows how  to do it using the anchor and iurl tags
