Here you can digest how to use Wikipedia, in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
To search a specific namespace, include the prefix in searches
To search for a topic in a specific namespace, precede the topic with that namespace's prefix, followed by a colon. If the topic has a page with that name, pressing Enter will take you right to it. Otherwise, a list of relevant search results will appear.
For example, one way to get a listing of articles on ancient Greece is to type Category:Ancient Greece in the search box. To go to the portal for the Ancient Greeks, you would type: Portal:Ancient Greece.
The namespace prefixes are: Category:, Portal:, File:, User:, Talk:, Wikipedia:, Help:, Book:, Draft:, and Template:.
You can also search in sister projects by using the full name of the sister project, or its abbreviation (e.g.- Wiktionary: or wikt:).
Sometimes it is necessary to refer to a specific section of a page when linking, rather than to the whole page.
You can create a link to any subheading on any page in Wikipedia by including a # character followed by the subheading at the end of a link. For example:
For a listing of current collaborations, tasks, and news, see the Community portal. For a listing of ongoing discussions and current requests, see the Dashboard.
