 What are filters? Moodle has a number of filters which affect how elements of the course are displayed. This video displays in its own player because the multimedia plugins filter has been activated. To see which filters your Moodle administrator has made available we click the cog icon and then click filters. Note that we can view and change filters for individual activities from the cog menu inside each activity as well. We now on the course filter settings page where we see a list of filters for the course. Activity names auto-linking is useful because it means we can refer to an activity in the course simply by typing its name in a different area and it will link to that activity. The multimedia plugins filter is enabled so we can display our sound and video files in a player. Glossary auto-linking means that if we add a key term to a glossary and then type that key term somewhere on the course it would automatically link to its glossary entry. Let's go into the course and add a couple of items to see how these filters work. So I'm turning the editing on and then in the section writing let's type a sentence which includes two possible filters. So adjective would link to a glossary entry and activity auto-linking would link to another activity on the course page. If we now save the changes there we have the word adjective and if we hover our cursor over the word adjective it takes us to the glossary entry which we made in a previous video. The words key grammar terms are linked to that glossary.
