DokuWiki can mark abbreviations and acronyms (terminology) automatically. If your browser supports the <acronym> tag, you can hover your mouse on an abbreviation to see a short explanation, shown as a tooltip. For example, if the mouse is positioned over XML (which is included in the default acronyms list), the tooltip displays Extensible Markup Language.

Some preconfigured examples:

• BTW, CMS, FAQ, HTML, WYSIWYG

Note: only full words will be marked. Eg. an acronym that is used within a word will not result in a acronym tooltip. Example: XML is an acronym, myXML is not.

At some point, the supported tag will switch from <acronym> to <abbr>¹⁾ as DokuWiki becomes more HTML5-compliant. There is a general feature request in the bug tracker but it is not targeted for any particular release.

• DokuWiki's standard abbreviations are stored in the conf/acronyms.conf file. You can add your own abbreviations by creating a conf/acronyms.local.conf file and placing your abbreviations
• The acronyms file has to be encoded in UTF-8.
• Because it is reserved to mark a comment line, a hash (#) needs to be escaped by a backslash (\#)
