not sure what it is you're asking, so i'm guessing you want to link from one article to another?
if thats the case then you've either got to use the editor or do the code yourself. if you are using the editor highlight whatever text you are going to sue as the link and then click on the insert link option
if you are not using the editor then you must write the code yourself
<a href="the url to the other article">the text that will be the link</a>
