Not your “ordinary” wiki, DokuWiki has its own unique ways of doing things and there have been many times when I have had to go digging around for answers. Since these instances are piling up, I figured it's time to start a DokuWiki-specific page.

The official DokuWiki manual

There is no “delete” button. Instead, a DokuWiki page is deleted by editing the page in question, erasing all the content, and then saving the page.

Surround the link with “%%“.

End a line with “\\”.

Access Configuration Settings and set “Maximum section edit level” to 0.
