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.
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.
