Typical wiki pages are named by removing the spaces between two or more words and starting each word with a capital letter. Just using such a WikiWord links to the page if it exists, otherwise it will be displayed with a question mark link, like SampleUndefinedPage?. The question mark indicates the page doesn't exist yet and is a link to create it.
Links to pages that are not a WikiWord are done by surrounding the text with two pairs of square brackets like [[Sample Free Link]].
The : prefix is another way to link within the wiki, and may be required for links to subpages of parent pages that are not WikiWords. For example: Local:Help/Macros = Help/Macros
See /Subpages
You can separate a WikiWord from adjacent text with the special "" (two double-quotes) delimiter. The "" delimiter is not displayedit is useful for plural forms of page links like WikiWords. In nearly all cases trailing punctuation is ignored, so you can safely make links like http://deoxy.org/, without the trailing comma being part of the link. You can also use [[freelink]]s.
To make on-site links you must respecify the protocol e.g.:
Use brackets for a footnote link to the image's URL:
Make an image into a link like this:
Align image left or right (with optional padding, in pixels):
For more control with images use HTML.
