The "Narrow Margins" and "Wide Margins" menu 
items reset TheCurrentLeftMargin and 
TheCurrentRightMarginproperties of the 
HTDisplayBox component. These items add pixels to 
the left edge and determine whether a new line is 
started for the right edge if the 
WrapHyperTextDisplayLines property is true. Narrow 
margins uses 20 pixels from each edge of the display 
and wide margins uses 40 pixels.
