Joomla newbies often ask how to link text in one content item to another. There are several different ways to do this; here I describe one easy method using JCE Editor.
First, insure that JCE Editor is installed and its advanced link plugin is enabled, because that’s what we’ll be using. The plugin you want is named “advanced link”; don’t confuse it with the basic link plugin named simply “link”.
Open for editing the content item you wish to link from. By “content item” I mean anything you can add text to: articles, sections, categories, whatever. Assuming your text is already written, select the word(s) you want to link from. Press the Insert/Edit Link button; a dialog window opens. In the portion of the window labeled “Link Browser”, navigate to the content you want to link to. If you’re not sure where to look, open “Content” and look inside it. Find the content item you wish and click on it to select it. (It does not change appearance to show that it has been selected, but notice that the URL field at the top of the window now has the selected element’s URL. Press “Insert”. The dialog window closes.
Press “Apply” or “Save” in the content item’s editing window and you are done. If you want to check your work (and I suggest you do), open your content item in a separate browser tab and check that the new link exists and works.
