Cygwin + RXVT + GNU Emacs: Key Missing

[zhaoway]

My environment is Cygwin RXVT and GNU Emacs in console mode.

Emacs can't catch the following keys as C-h k returns either nothing or weird combo.

C-h k on:

ctrl up => Esc O a
shift tab => TAB
ctrl tab => no effect at all

Please help!
Thanks!

When you hit those keys, Emacs gets some escape sequences from the
terminal. Often, the escape sequence from the terminal is the same
when you hit Tab and Shift-Tab, say. Thus, Emacs obviously can't
distinguish the keys.

If your terminal is programmable, then you can tell it to send
different escape sequences. After this, you can teach Emacs about
them.
