The Style Template editor allows for changing the background and text color of the page and the sections below, as well as inserting links, images, and styled Lists. However, Bold, Italic,..., xl, xxL etc. do not have the UNDO function. However, instead of undo, you can highlight the text, cut, paste as unformatted text and redo the styling
For more involved editing, use a word processor or wysiwyg html editor. Style and design as you like; copy from the editor and paste the content into any editable section of this document.
Images can't be copied from editors. Insert them separately
