Announce that the next input line starts a definition of the |
|
.Ar term . |
|
This macro must appear alone on its own input line. |
|
The argument defaults to the first argument of the first macro |
|
on the next line. |
|
The argument may not contain whitespace characters, not even when it is quoted. |
|
This macro is a |
|
.Xr mandoc 1 |
|
extension and is typically ignored by other formatters. |

|
When viewing terminal output with |
|
.Xr less 1 , |
|
the interactive |
|
.Ic :t |
|
command can be used to go to the definition of the |
|
.Ar term |
|
as described for the |
|
.Ev MANPAGER |
|
variable in |
|
.Xr man 1 ; |
|
when producing HTML output, a fragment identifier |

|

|
.Pp |
|
In most cases, adding a |
|
.Ic \&Tg |
|
macro would be redundant because |
|
.Xr mandoc 1 |
|
is able to automatically tag most definitions. |
|
This macro is intended for cases where automatic tagging of a |
|
.Ar term |
|
is unsatisfactory, for example if a definition is not tagged |
|
automatically (false negative) or if places are tagged that do |
|
not define the |
|
.Ar term |
|
(false positives). |
|
When there is at least one |
|
.Ic \&Tg |
|
macro for a |
|
.Ar term , |
|
no other places are automatically marked as definitions of that |
|
.Ar term . |
