Hi, We already talked about something similar some time ago. I see [.RS 4] and [.RS +4n] used in the man pages. And there are also [.in +4n] and I think I've also seen [.in 4]. Is there any difference between [+4n] and a simple [4]? Which is the preferred one? And BTW, does [.RS] do anything different than [.in]? I guess the code implementing those macros is written somewhere. Where can I have a look at that code to see it myself? Thanks, Alex
