Umb10 - I'm trying to create a custom tinymce button (is that a command or plugin in their speak?) and have managed to get the option to show in the RTE datatype screen (without an icon). I can't for the life of me, get the button to show in the RTE itself though. I've tried adding the init code to a js file in the App_Plugins folder, but that just throws a tinymce error. If I create a plugin.min.js file at this location wwwroot\umbraco\lib\tinymce\plugins\glossaryTerm it doesn't seem to get picked up. What am i doing wrong? appsetting.json "Umbraco": { "CMS": { "RichTextEditor": { "Commands": [ { "Alias": "glossaryTerm", "Name": "Glossary Term", "Mode": "Selection" } ] } } }
