+
+### Description
+
+   These functions manipulate a window that contain Soft Label Keys
+   (SLK). To use the SLK functions, a call to slk_init() must be made
+   BEFORE initscr() or newterm(). slk_init() removes 1 or 2 lines from
+   the useable screen, depending on the format selected.
+
+   The line(s) removed from the screen are used as a separate window, in
+   which SLKs are displayed.
+
+   slk_init() requires a single parameter which describes the format of
+   the SLKs as follows:
+
+    0       3-2-3 format
+    1       4-4 format
+    2       4-4-4 format (ncurses extension)
+    3       4-4-4 format with index line (ncurses extension)
+    2 lines used
+    55      5-5 format (pdcurses format)
+
+   slk_refresh(), slk_noutrefresh() and slk_touch() are analogous to
+   refresh(), noutrefresh() and touch().
+
+### Return Value
+
+   All functions return OK on success and ERR on error.
+
+### Portability
