UK TeX FAQ -- question label overstrike

### Overstriking characters

This may be used, for example, to indicate text deleted in the course of editing. Both the ulem and the soul packages provide the necessary facilities.

Overstriking for cancellation in maths expressions is achieved by a different mechanism.

Documentation of ulem is in the package file.

`soul.sty`
  macros/latex/contrib/soul (zip, browse)
`ulem.sty`
  macros/latex/contrib/misc/ulem.sty
