The keycodes start at KEY_MAX, but are not guaranteed to be
the same value for different runs because user-defined codes are
merged from all terminal descriptions which have been loaded.
This is the case that X/Open Curses documented.

Likewise, the \fBmeta\fP(3X) function allows the caller to change the

is not provided by other implementation of curses.
