## Arbitrary Page Names

If you enclose a sequence of characters in square brackets and double quotes `["like this"]`, that makes it a page name. That can be used for specific uses of [[MoinMoin|MoinMoin]] (like organizing a list of items, e.g. your CD collection, by their "natural" name), or if you want to create a wiki with a non-western character encoding.  

/!\ **This is a configurable feature enabled by `allow_extended_names`, so it might not work!** 


## URLs and Inline Images

There are several way to insert external references[^1] into the text: 

* direct URL insertion; if the URL ends in an image extension ("`.gif`", "`.jpg`" or "`.png`"), the URL is converted to an image tag. 
* bracketed URLs. 
* [[InterWiki|InterWiki]] links. 
* email addresses. 
If you enter URLs into normal text, there is the problem of detecting what belongs to the URL and what not. There are four ways to force the ending of an URL: 

* put a space after the URL. 
* use the [[!c2 SixSingleQuotes desc="SixSingleQuotes"]] escaping. 
* put the URL into double quotes. 
* use the bracketed URL syntax. 
The supported URL schemes are: `http`, `https`, `ftp`, `nntp`, `news`, `mailto`, `telnet`, and `file`. The administrator of your wiki can extend the supported schemes by using the `config.url_schemas` variable (see [[HelpOnConfiguration|HelpOnConfiguration]]). 

In addition to the standard schemes, there are [[MoinMoin|MoinMoin]]-specific ones: `wiki`, `attachment`, `inline`, and `drawing`. "`wiki`" indicates an [[InterWiki|InterWiki]] link, so `MoinMoin:FrontPage` and `wiki:MoinMoin:FrontPage` are equivalent; you will normally prefer the shorter form, the "`wiki`" scheme becomes important when you use bracketed links, since there you always need a scheme. The other three schemes are related to file attachments and are explained on [[HelpOnActions/AttachFile|HelpOnActions/AttachFile]]. 

When the configuration option `bang_meta` is set to true, you can surpress [[WikiName|WikiName]] linking by putting an exclamation mark (_bang_) before the [[WikiName|WikiName]], i.e. `!WikiName`. This is deactivated by default. 

For more information on the possible markup, see [[HelpOnEditing|HelpOnEditing]]. For details on how to link to subpages, see [[HelpOnEditing/SubPages|HelpOnEditing/SubPages]].
