Noob link question

I have seen that people in blogs post links and instead of seeing the whole web address you see something like the word CLICK HERE. How do I add a link, then change what the text says? Thanks

Every word you type can be a link...you just highlight it and then click the link button next to the image button...type the link in the "Link URL" section and then save the link...there you go. :)

Highlight a line of text and either click the image third to the right(a little chain) above your post query, or press CTRL + SHIFT + L

Wow guys all three of you thanks for the help. I figured that little link button had somthing to do with it. Just wasnt sure.
