<P>
On VT100s and their software emulations, such as X terminal emulators,
there are normally at least four function keys (<tt class="constant">KEY_F1</tt>,
<tt class="constant">KEY_F2</tt>, <tt class="constant">KEY_F3</tt>, <tt class="constant">KEY_F4</tt>) available,
and the arrow keys mapped to <tt class="constant">KEY_UP</tt>, <tt class="constant">KEY_DOWN</tt>,
<tt class="constant">KEY_LEFT</tt> and <tt class="constant">KEY_RIGHT</tt> in the obvious way. If
your machine has a PC keybboard, it is safe to expect arrow keys and
twelve function keys (older PC keyboards may have only ten function
keys); also, the following keypad mappings are standard:

<P>
The following table lists characters from the alternate character set.
These are inherited from the VT100 terminal, and will generally be
available on software emulations such as X terminals. When there
is no graphic available, curses falls back on a crude printable ASCII
approximation.
<b>Note:</b> These are available only after <tt class="function">initscr()</tt> has
been called.
