Sometimes TinyMCE (and the small window of an HTML field) are not the best way to edit a knowledge article. Using the capabilities of the Service Portal it is possible to create a widget which, together with a WYSWYG editor, can make it easier to create or edit knowledge articles.

One of them is CKEditor.

Here you can find a good list of main features https://ckeditor.com/docs/ckeditor4/latest/features/index.html

Some of them are:

• Pasting Content from Microsoft Word
• Pasting Content from Microsoft Excel
• Inserting Code Snippets
• Mathematical Formulas
• Real-time PDF Export

This simple application adds a UI Action that allows you to edit the knowledge article in a dedicated page of the Service Portal –> https://github.com/mrwalakala/sn-sp-ckeditor
