Wiki:Redirect

A redirect is a page created so that navigation to a given title takes the reader directly to a different page. A redirect is created using the syntax:

#REDIRECT [[Target]]

...where "target" is the name of the target page. It is also possible to add a section header to make a redirect to a specific section of the target page in the following manner:

#REDIRECT [[Target#Section header]]

The pound/number/hash sign (#) is also used to link to page anchors.

See Help:Redirect at Wikipedia. Most of content there will apply to OSM Wiki, especially technical parts.
