- Upon initializing curses, a default window called <STRONG>stdscr</STRONG>, which is the
- size of the terminal screen, is created. Many curses functions use
- this window.

+ For <EM>curses</EM> to distinguish the ESC character resulting from a user's
+ press of the "Escape" key on the input device from one beginning an
+ <EM>escape</EM> <EM>sequence</EM> (as commonly produced by function keys), it waits after
+ the escape character to see if further characters are available on the
+ input stream within a short interval. <STRONG>ESCDELAY</STRONG> stores this interval in
+ milliseconds.
+
+ If <STRONG><A HREF="curs_inopts.3x.html">keypad(3x)</A></STRONG> is disabled for the <EM>curses</EM> window receiving input, a
+ program must disambiguate escape sequences itself.

+ The <EM>curses</EM> library converts a tab character to this number of spaces as
