spell checker in nroff mode?

[Luke Huang]

Hi all

I am not a English native speaker so that I always open spell checker on-the-fly. It works pretty well even if in programming. But, it's a bit inconvenient when it works when I am writing troff file.

For example:

\fBPhysical Address\fP

In this case spell checker highlights \fBPhysical as a wrong word. How can I avoid this? (either in an Emacs way or in a troff way)

Thanks a lot for your help

Luke
