Hello @Ernesto, glad to hear you enjoy Webflow
Here is one of the announcements where Webflow team shows how to add different type of content into the Rich text element: http://forum.webflow.com/t/new-feature-rich-media-embeds-in-the-rich-text-editor/23294
Basically:
- for removing some part of Rich text element you make double click with the mouse and simply use āDeleteā or āBackspaceā on your keyboard (like you would delete some text);
- for adding something to Rich text, you make double click with the mouse, put cursor in the place where you want to add new element and press āEnterā on your keyboard
