.SH DESCRIPTION
-The \fBslk\fP* functions manipulate the set of soft function-key labels that exist on
-many terminals.
+The \fBslk\fP* functions manipulate the set
+of soft function-key labels that exist on many terminals.
For those terminals that do not have soft labels,
\fIcurses\fP takes over the bottom line of \fB\%stdscr\fP, reducing the size of
\fB\%stdscr\fP and the variable \fBLINES\fP.
it does not try to use any hardware support for this
mode.
.SS Initialization
-The \fB\%slk_init\fP routine must be called before \fB\%initscr\fP or \fB\%newterm\fP
+The \fB\%slk_init\fP routine must be called
+before \fB\%initscr\fP or \fB\%newterm\fP
is called.
If \fB\%initscr\fP eventually uses a line from \fB\%stdscr\fP to
emulate the soft labels,
It has an effect only
if soft labels are simulated on the bottom line of the screen.
.PP
-Because \fB\%slk_color\fP accepts only \fBshort\fP (signed 16-bit integer) values,
+Because \fB\%slk_color\fP accepts
+only \fBshort\fP (signed 16-bit integer) values,
this implementation provides
\fB\%extended_slk_color\fP which accepts an integer value, e.g., 32-bits.

.SH EXTENSIONS
-X/Open \fIcurses\fP documents the \fIopts\fP argument as reserved for future use,
+X/Open \fIcurses\fP documents the \fIopts\fP argument
+as reserved for future use,
saying that it must be null.
This implementation
uses that parameter in ABI 6 for the functions which have a color-pair
interpreting that as a comma-separated list of numbers,
e.g., \*(``3,2,3\*('' for the 3-2-3 layout.
.IP
-Finally, if there is no \fBfln\fP capability, \fB\%slk_start\fP returns \fBERR\fP.
+Finally, if there is no \fBfln\fP capability,
+\fB\%slk_start\fP returns \fBERR\fP.
.bP
If \fB\%slk_start\fP is given a non-null \fIgp\fP,
it copies the \fIng\fP elements of the group of soft-keys, up to 16.
