runoff.set.tabs

clears previous tabstops and specifies tabstop locations at specified column position{s}.

The tabstops (up to 30) must be greater than zero and in increasing order. They indicate tabstop positions relative to the left margin.

Tabs are only in effect in .'nofill' mode.

The left-tab character '(<)' causes the next word to start at the next tab position. The right-tab character '(>)' causes the next word to end at the next tab position.

If a tab character appears at a point in the line where no further tab stops have been set, the tab character is ignored.
