Styles allow flexibility and are easily changed through the Styles screen. If you change a style in the Styles screen, the document will also be effected. For example, you used an 18pt. Then you change the style to a 10pt. Throughout the document, the 18pt.
Styles are codes in a document and macros run once in a document.
Both macros and styles help to streamline editing documents. You may use WordPerfect's macro capability to create a macro which will turn on any of your styles. Type 1 or N and type a name for the style. This name can be as long as eleven characters. IF you want to change the type of style to open.
