One argument is required; additional arguments are ignored. |

Currently, the only argument implemented is |

requesting to keep together all words of the contained text |

The name of the manual page, or \(em in particular in section 1, 6, |
|
and 8 pages \(em of an additional command or feature documented in |
|
the manual page. |
|
When first invoked, the |
|
.Sx \&Nm |
|
macro expects a single argument, the name of the manual page. |
|
Usually, the first invocation happens in the |
|
.Em NAME |
|
section of the page. |
|
The specified name will be remembered and used whenever the macro is |
|
called again without arguments later in the page. |
|
The |
|
.Sx \&Nm |
|
macro uses |
|
.Sx Block full-implicit |
|
semantics when invoked as the first macro on an input line in the |
|
.Em SYNOPSIS |
|
section; otherwise, it uses ordinary |
|
.Sx In-line |
|
semantics. |
