This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Labels in the text styling drop-down list¶
In the selectlist, both, the label and the class selector or class name may be shown:
class name - label
label - class name
Labels are always shown in the author's language regardless of the content's language.
The order is alphabetical.
