Hi there

In order to add a hyperlink to your document you can highlight a paragraph or a certain number of words then use the shortcut command+k or control+k depending on whether you are on mac or windows respectively. Then you can insert the URL's into that pop-up box. When you want to access this link you must un-click the text then input command+shift+left-click or control+shift+left-click depending on whether you are on mac or windows respectively. If this didn't help answer your question please clarify a little more in depth as to what you are trying to do and I would be more than happy to help out!
