Styles and Format in WYSIWYG fields

Seeking documenation or instructions on how to modify Styles and Formats in text fields.

Also have WYSIWYG module version 1.2 (New field WYSIWYG ) By Urdhva Tech installed. Do not see options for styles.

It’s been a while since I did it. But you can’t use it on existing fields. You have to create a new one with the type of “WYSIWYG” and then when you put the field on the front end you get a TineMCE editor window instead of the standard text field.
