.El End-list..It List item.MANUAL AND GENERAL TEXT DOMAIN MACROSThe manual and general text domain macros are special in that most of them are parsed for callable macros for example:.Op Fl s Ar fileProduces [-s file]In this example, the option enclosure macro ‘.Op’ is parsed, and calls the callable content macro ‘Fl’ which operates on the argument‘s’ and then calls the callable content macro ‘Ar’ which operates on the argument ‘file’. Some macros may be callable, but are notparsed and vice versa. These macros are indicated in the parsed and callable columns below.Unless stated, manual domain macros share a common syntax:.Va argument [ . , ; : ( ) [ ] argument ... ]Note: Opening and closing punctuation characters are recognized as such only if they are presented one at a time. The string ‘),’ isnot recognized as punctuation and will be output with a leading white space and in what ever font the calling macro uses. The argumentlist ‘] ) ,’ is recognized as three sequential closing punctuation characters and a leading white space is not output between the char‐acters and the previous argument (if any). The special meaning of a punctuation character may be escaped with the string ‘\&’. Forexample the following string,.Ar file1 , file2 , file3 ) . Produces file1, file2, file3).Manual Domain MacrosName Parsed Callable DescriptionAd Yes Yes Address.

Macro names ending in ‘o’ begin a quote which may span more thanone line of input and are close quoted with the matching macro name ending in ‘c’. Enclosure macros may be nested and are limited toeight arguments.Note: the extended argument list macros (‘.Xo’, ‘.Xc’) and the function enclosure macros (‘.Fo’, ‘.Fc’) are irregular. The extendedlist macros are used when the number of macro arguments would exceed the troff limitation of nine arguments.The macros UR (starting a URI/URL hypertext reference), UE (ending one), and UN (identifying a target for a reference) are also avail‐able.
