If you site has been configured to use a "rich editor," the text area where you enter the content of your pages will be "WYSIWYG" (what you see is what you get) and you will have a variety of buttons and menus at your disposal for formatting your text.

Document section headers: Use the "Format" dropdown box to select section headers, such as h2, h3, h4, and so on.

Pasting from other applications: You generally want not to preserve formatting from other applications, like Word, when you are copying and pasting into the editor window. You can use the "paste from word" button (the one that looks like a clipboard with a Word logo on it) to help strip out unwanted formatting that is going to make your page look bad.

Adding hyperlinks: Use the "link button" (the one with the globe and chain links) to add hyperlinks to other pages. First, type the text that you want to make into a link, then highlight it, and then press the button. For links to other sites, it should be self-explanatory. For internal links, to pages within your site, you probably want to use the internal link format of href attribute. In this case, after you press the "link" button, select "other" in the "Protocol" dropdown, and type internal:node/nn in the URL box, where "nn" is the node to which you want to link. (See the page on internal links for more information.)
