First, you need to make sure your terminal sends some useful byte-sequence
when you press those keys.  Most terminal emulators send the same sequence
for shirt-right than for right, so Emacs simply can't tell the difference.

Once your terminal emulator is properly configured you need to tell Emacs
what that seuqnce is by appropriate (define-key function-key-map ...) calls.
See lisp/term/xterm.el for some default settings used if your terminal
is xterm.  The same terminal emulator may send different sequences
depending on the configuration, so there's no standard sadly.

I.e. in your xterm, the backspace key sends code 127 (aka C-?) whereas in
your aterm it sends code 8 (aka C-h).  Fix your aterm config.

M-x xterm-mouse-mode might help.  I don't know if aterm supports this
xterm-specific extension.
