Important: #85361 - EXT:rte_ckeditor - re-add the soft hyphen button

See forge#85361


With the switch from htmlArea to CKEditor the soft hyphen button was gone. This functionality is now re-added as custom CKEditor plugin.

It is loaded like each other existing CKEditor plugin in the TYPO3 core via EXT:rte_ckeditor/Configuration/RTE/Editor/Plugins.yaml. It's automatically loaded in the RTE presets "default" and "full". The shortcut Ctrl + - for adding a soft hyphen works without showing the button in the CKEditor button bar.


By using the shipped RTE presets "default" or "full", the functionality and the toolbar button is automatically added to CKEditor toolbar. This helps the editor immensely to create better content for the responsive web these days.

How to activate the functionality in a custom RTE preset

The functionality is automatically added if you are importing EXT:rte_ckeditor/Configuration/RTE/Editor/Plugins.yaml in your custom RTE preset. If your custom RTE preset can't rely on that file, you can explicitly import this plugin as shown:

      resource: "EXT:rte_ckeditor/Resources/Public/JavaScript/Plugins/softhyphen/"
      # set whether the shortcut for this plugin is activated or not
      enableShortcut: true

How to add the button in a custom RTE preset

The button with the buttonName softHyphen of the plugin is assigned to a toolbarGroup named insertcharacters. Based on how you like to configure the toolbar in your RTE preset you must either use the toolbarGroup or the buttonName to display the button at the desired location in the toolbar.

Please take look into the supplied RTE presets to see working examples:

  • EXT:rte_ckeditor/Configuration/RTE/Default.yaml
  • EXT:rte_ckeditor/Configuration/RTE/Full.yaml
