Editing Your Page
Let's start with the edit tabs, which affect how you interact with the file you are working on:

When you want to work on changing your file, use the "Normal" tab: . Most of the time you will have this tab selected. This is active whenever you start up the program.
When you want to PREVIEW the page and test out some of the links (the ones that move within your own pages - it won't work for your outside links), select teh "Preview" tab. This can be useful after you have made an anchor and you want to try it out. (More on anchors later)
If you are feeling brave, you can view the actual HTML code that is used to define your page on the web. Most of the time, you won't have to worry about it. Select the "Source" tab to view the raw HTML code.
If you want to see your page with all of your HTML tags shown, select the "HTML Tags" tab. This shows where in your page your various HTML tags begin and end. You will probably not need this view.
