name showlabels category Package shortdesc Show label commands in the margin. longdesc This package helps you keep track of all the labels you define, by longdesc putting the name of new labels into the margin whenever the \label longdesc command is used. The package allows you to do the same thing for longdesc other commands. The only one for which this is obviously useful is longdesc the \cite command, but it's easy to do it for others, such as the longdesc \ref or \begin commands. [description copied from TeX Catalogue]
