+typesetting position to @code{<length>} from the left margin of the paragraph.
+If the typesetting position is already further along, @code{\\tabto} starts a
+new line; the command @code{\\tabto*} will move position backwards if
+necessary, so that previous text may be overwritten.  In addition, the command
+@code{\\TabPositions} may be used to define a set of tabbing positions, after
+which the command @code{\\tab} advances typesetting position to the next
+defined ``tab stop''.")
