Use viewing modes when you want to read or move around in a document.
To read a document with a minimum of eye strain and with tools optimized for reading, use reading layout view (reading layout view: A view that is designed for reading documents on a computer screen. The document is resized to fit the screen and most toolbars are removed, but commands are available for navigating, commenting, and looking up words.).
Reading layout view is designed to make reading documents on the screen more comfortable. In this mode, Word removes distracting screen elements, such as extraneous toolbars. Word also uses your computer's screen resolution settings to size the document for optimum readability.
In reading layout view, you can use the Document Map (Document Map: A vertical pane along the left edge of the document window that displays an outline of the document's headings. You can use the Document Map to quickly move through a document and to keep track of your location in it.) or thumbnails to jump to different sections of the document, and you can use a task pane for reading-related activities, such as looking up or translating a word. If you want to edit the document, click where you want to make changes, and edit the document normally.
Reading layout view does not display the document the way the document is formatted for printing. Text may appear larger than expected, and the page breaks do not necessarily correspond to breaks between printed pages.
To switch to reading layout view, click Read on the Standard toolbar or press ALT+R.
To turn off reading layout view, click Close on the Reading Layout toolbar or press ALT+C.
