Look Both Ways
Further reflecting its split personality, TextEdit presents text in two different ways, wrapped-to-window and wrapped-to-page, both of which can be used in either plain or rich text modes. When text is wrapped to the window, it completely fills the document window; the bigger the window, the more text you will see. But if the text is wrapped to the page instead, TextEdit shows the text within the margins of a printed page; in other words, in the traditional style of a WYSIWYG word processor. When using TextEdit for documents that will be printed or shared via PDF files, wrap-to-page mode is very useful. To quickly toggle between these two viewing modes, use the Command+Shift+W keyboard shortcut or select the appropriate item under the Format menu.
