Download and install the directory named wikipediacalls into the /moodle/filter/ directory. Enable the filter at Site Administration | Modules | Filters | Manage filters.

The filter can be used to create links to Wikipedia entries around a course site, including text inside labels, web pages, forum posts, assignment descriptions, and so on.

When entering text in a Moodle editor, the Wikipedia filter code can be placed immediately after the target word in [square brackets]. Do not put spaces between the word and the brackets.

The most basic filter code is an upper case [WP] after the word you want linked. The word will then be passed as a search term to Wikipedia.

Two additional optional codes can be added to the WP code. If the desired search term differs from the word being linked, the desired search term(s) can be provided as a second code, separated from the WP code with a vertical bar |. This | symbol is accessible on a keyboard, usually by holding Shift and pressing the backslash key. Multiple search terms can be used in this second code, separated by spaces or underscore _ characters. The desired language for the target Wikipedia entry can be suggested as a third code, again following a vertical bar |. Language codes are two letter abbreviations, for example en, es, nl, ru, and so on.

If you would like to form the link around more than one word on a Moodle page, you can use an underscore character between words, for instance Turing_Test[WP].

With the Wikipedia filter on, words followed by [WP] codes are rendered as links:

Target words are turned into links to Wikipedia entries. Clicking on a link conveniently opens Wikipedia in a new tab or browser window.

Here are some ideas for how you could employ the Wikipedia filter in teaching:
