82: When using
83: .Fl c ,
84: most terminal devices are unable to show the markup.

90: .Xr col 1
91: .Fl b
92: instead.

157: .It Fl S Ar subsection

! 226: falls back to looking for files called
! 227: .Ar name . Ns Ar section .
1.1 schwarze 228: If both a formatted and an unformatted version of the same manual page,
229: for example
230: .Pa cat1/foo.0

240: .Bl -tag -width MANPATHX
241: .It Ev MACHINE

1.15 schwarze 262: If
263: .Xr less 1
264: is used, the interactive
265: .Ic :t

1.1 schwarze 288: .It Ev MANPATH
289: The standard search path used by
290: .Nm
