This documentation is not using the current rendering mechanism and is probably outdated.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.
Configuring the anchor accessibility feature¶
The anchor accessibility feature allows to attach special accessibility features to CSS classes when they are applied to links with the TYPO3 element browser. For example, icons may be inserted in front or at the end of links when configured classes are assigned to the links.
The Extension Manager must be used to enable the feature.
The TYPO3 element browser must be enabled in the 'Insert/Modify link' dialogue by setting property buttons.link.TYPO3Browser.disabled to 0 in Page TSconfig. The TYPO3 element browser is enabled by default in the backend, but never available in the frontend.
The classes should first be defined in the CSS file specified by RTE.default.contentCSS.
The classes should be part of the list specified by property RTE.default.classesAnchor.
The accessibility features attached to the classes are specified by property RTE.classesAnchor.
