There are several way to insert external references 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 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 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 wiki.
