I'm using Heirloom doctools on OpenBSD. I'm using the version on the ports system[1]. I'm trying to use the .CW macro to mark a text in typwriter font (courier). But it does not work. Using \f(CW works, however.
Does .CW work at all on -ms with Heirloom doctools? [1]: https://openports.se/textproc/heirloom-doctools
