Screenshot of WordPerfect (version 8), with Reveal codes on (below) and a customized toolbar placed to the right on the screen. WordPerfect allows for almost unlimited customization of toolbars, menus and the keyboard; shown is the keyboard customization menu. Reveal codes, in itself sufficient reason to use WP, allows complete access to formatting codes in a document, making it possible to debug any formatting problem that might occur. In spite of statements to the contrary, MS Word has no effective substitute for this invaluable feature, with interminable and incurable formatting errors as a result. WordPerfect also includes extensive search and replace possibilities of formatting codes.
