The link window:
To ad a link to text, select the text then click on the link button, find the page or menu link you want to link to. Click the Insert button. It is advisable to link always to menu links and not individual pages, unless those pages are floating pages (not linked by a menu). This way, should the menu ever change, the link won’t be broken. Joomla will simply update the link paths.
To add a link to an image, select it and click on the editor link tool. A popup will let you navigate to the content you want to link to, or you can enter an external link. The same applies to text, select the text you want to link and click on the link icon to link it to the content you want to link it to.
To link to an article: click on content and find the article under the category it belongs to.
To link to an email address: click on the envelope icon and enter the email that you want to link to.
To link to a PDF or doc: select the text or image you want to add the link to, click on the link button, then click on the browse button. Find the document you want to link to, click the Insert button. I usually place PDFs in a PDF folder to keep them separate from the images folders. You can also add a new folder for docs.
