For example, \special{pause} is used in TeX as follows.
% Keep the page size
\special{dviout `keep y}
% Screen 800 x 600: draw off, white screen
% bottom cover sheet On for Pause
% Presentation mode; wait
% draw on, Fit screen
\special{dviout -y=SVGAP !AN0N5NP!p;!bdf}
...
\special{pause}% the place to pause
...
\special{pause}% the place to pause
...
In this case, if the corresponding dvi file is previewed from the first page, it is shown in Presentation Mode. The clickings of [Space]key moves the cover sheet to the position indicated by \special{pause}.
