### Output Options

- `int idlok(win, bf)`
  `void idcok(win, bf)`
  Enable or disable terminal's insert/delete features for the window (idlok(...) for lines and idcok(...) for characters). (Note: idcok(...) not implemented yet.)
- `void immedok(win, bf)`
  If set TRUE, every change to the window `win` will cause a refresh to the physical screen. This can decrease the performance of a program, so the default value is FALSE. (Note: not implemented yet.)
- `int clearok(win, bf)`
  If `bf` is TRUE the next call to wrefresh(win) will clear the screen and redraw it completely. (as in the editor vi when you press CTRL+L).
- `int leaveok(win, bf)`
  The default behavior is for ncurses to leave the physical cursor in the same place it was on the last refresh of the window. Programs which don't use the cursor can set leaveok(...) TRUE and save the time normally required for cursor motion. In addition, ncurses will try to make the terminal cursor invisible.
- `int nl()`
  `int nonl()`
  Control the translation for newline. Turned on with nl() will translate a newline in carriage return and line feed on output. nonl() will turn translation off. With disabled translation ncurses can do faster cursor motion.
