Questions tagged [discretionary]
{discretionary} is for questions about the TeX primitive \discretionary (or variants thereof, such as LaTeX's \- shortcut), used to typeset text conditionally in a line break or otherwise. Questions about {discretionary} may also use the {line-breaking} and/or {hyphenation} tags, if appropriate. Questions about discretionary ligatures should be tagged {ligatures} instead.
