A document-oriented editor. LisaWrite normally shows text as a series of lines following one another (see the check symbol beside the “Don’t Preview Pages” command). If we were to select the preview mode, the white space at the top and bottom of each page would appear along with any header or footer text.

A distinct advantage of a bit-mapped display is that it can accurately represent different type faces, justified lines, actual spacing between lines as well as many other useful things. The height of the vertical rule following the paragraph ending with “Stereo Sales Representatives” indicates the line spacing separating paragraphs.
