Quanta's editor window
At the top of the editor window is the editor toolbar set. Currently, Quanta has a default set of toolbars that are loaded. These are Standard, Fonts, Tables, Lists, Forms, Other. These are the original toolbars that have been a part of Quanta for some time now. These toolbars are strictly HTML and will continue to be a part of Quanta but will eventually be loaded only on demand and not by default.
Toolbar usage is pretty straight forward. If you're looking for a basic tag (like <u>), you click on that tag and it is inserted into your document. You then insert your information betrween (if there's a closing tag) the tags and call it good. If you're looking to insert something that takes more information than just you're text (like a <a href...>) then you'll get a dialog box with the various fields you can fill in.
