groff: Additional ms Macros
4.3.7.2 'groff' macros not appearing in AT&T 'troff'
....................................................
The 'groff -ms' macros have a few minor extensions compared to the AT&T
'troff -ms' macros.
-- Macro: .AM
Improved accent marks. ⇒ms Strings and Special Characters,
for details.
-- Macro: .DS I
Indented display. The default behavior of AT&T 'troff -ms' was to
indent; the 'groff' default prints displays flush left with the
body text.
-- Macro: .CW
Print text in 'constant width' (Courier) font.
-- Macro: .IX
Indexing term (printed on standard error). You can write a script
to capture and process an index generated in this manner.
The following additional number registers appear in 'groff -ms':
-- Register: \n[MINGW]
Specifies a minimum space between columns (for multi-column
output); this takes the place of the 'GW' register that was
documented but apparently not implemented in AT&T 'troff'.
Several new string registers are available as well. You can change
these to handle (for example) the local language. ⇒ms Strings and
Special Characters, for details.
