When you use a terminal, it sends escape sequences to the application
when you hit the cursor keys.  Many terminals send the same escape
sequence for, say, <left> and C-<left> and S-<left>.  So the
application (Emacs in this case) cannot distinguish them.

These days, terminals can be configured to send different escape
sequences for these cases.  Then you need to teach Emacs which escape
sequence stands for which keypress, and then you can bind these
keypresses normally.
