Aiuto:Parole magiche

A "magic word" is a symbol recognized by the MediaWiki software and which when seen in the non-commented text of the page, triggers the software to do something other than display that symbol, or transclude a page with that name, but instead to use the symbol directly.

A magic word can be:

• an upper case word, preceded and followed by two underscores, e.g. __NOTOC__
• an XML object, coded similar to HTML, preceded by "<" (and for the end tag "/") and followed by ">", as in <nowiki>...</nowiki>
• a parser function: similar to a template, a word preceded by the symbols "{{" and followed by "}}", and optionally parameter definitions between pipe characters, except that the part before the first pipe (or without pipes, the text between the braces) contains a colon (":"), e.g. {{ns:3}} and {{#ifexpr:{{{1}}}>3|large|small}}
• a variable: similar to a template without parameters, a word preceded by the symbols "{{" and followed by "}}", except the word used is in all upper case, e.g. {{CURRENTDAY}}
• a template modifier
• an image modifier

If a page in the template namespace has the same name as a magic word, the magic word will be invoked instead. If you discover you absolutely have to define a template with the same name as a magic word, prefix the name of the template with "msg:" or the name of the template namespace ("Template:"). See below for further details if you need this feature.

Tags which are used on this page such as "[MW1.5+]" indicate the MediaWiki version that first supported the magic word. "XYZ" indicates user input, which is used in the example.
