Adding links
1. Adding links to internal pages
Links to internal pages can be added by using WikiNames, [[double-bracket]] | forced links or AddingImages image actions:
Examples of links to an internal page
automatic link:
HomePage

forced link (the first part, before the | symbol, is the actual page name in the database; everything after that becomes the link description):
[[HomePage|index]] |
gives: HomePage index
image link (the link parameter points to the linked-to pagename):
{{image link="HomePage" url="images/email.gif" alt="email"}}
gives:

Links to external pages can be added by using (fully-qualified) literal URLs, [[double-bracket]] | forced links or AddingImages image actions:
Examples of links to an external page
automatic link:
http://www.w3.org/XML/
gives: http://www.w3.org/XML/
forced link (the first part, before the | symbol, is a fully-qualified URL; everything after that becomes the link description):
[[http://www.w3.org/XML/|Extensible | Markup Language]]
gives: Extensible Markup Language
[[Google:WikkaWiki]] |
image link (the link parameter should be a fully-qualified URL):
{{image link="http://www.w3.org/XML/" url="images/xml.png" alt="RSS feed"}}

Depending on the value of the external_link_tail parameter in the general ConfigurationOptions configuration options, external links can be differentiated by internal links by a specific tail (_)appended to the link. Further differences between internal and external links are controlled by the Wikka CSS stylesheets.

E.g. in some wiki engines I can make the anchor thus:
[[#foo]]
and then link to it:
[[MyPage#foo]]
How can I accomplish this task in Wikka?
