+       The <STRONG>touchwin</STRONG> and <STRONG>touchline</STRONG> routines throw away  all  opti-
        mization  information about which parts of the window have
        been touched, by pretending that  the  entire  window  has
        been  drawn  on.   This  is sometimes necessary when using
        overlapping windows, since a change to one window  affects
        the other window, but the records of which lines have been
        changed in the other window do  not  reflect  the  change.
-       The  routine <B>touchline</B> only pretends that <I>count</I> lines have
-       been changed, beginning with line <I>start</I>.
+       The  routine <STRONG>touchline</STRONG> only pretends that <EM>count</EM> lines have
+       been changed, beginning with line <EM>start</EM>.

-       The <B>wtouchln</B> routine makes <I>n</I> lines in the window, starting
-       at line <I>y</I>, look as if they have (<I>changed</I><B>=1</B>)  or  have  not
-       (<I>changed</I><B>=0</B>)  been changed since the last call to <B>wrefresh</B>.

-       The <B>is_linetouched</B> and <B>is_wintouched</B> routines return  <B>TRUE</B>
-       if  the  specified line/window was modified since the last
-       call to <B>wrefresh</B>; otherwise they return <B>FALSE</B>.   In  addi-

        The  XSI  Curses  standard,  Issue 4 describes these func-
        tions.
 
        Some historic curses implementations had,  as  an  undocu-
        mented  feature,  the  ability  to  do  the  equivalent of
-       <B>clearok(...,</B> <B>1)</B> by saying <B>touchwin(stdscr)</B>  or  <B>clear(std-</B>
-       <B>scr)</B>.  This will not work under ncurses.
