It's generating the expected keycode (we put ncurses into "keypad" mode,
so it produces single-value keycodes instead of escape sequences), but
this keycode is the same as for plain <Left>.  <Ctrl+Left>, <Shift+Left>
and plain <Left> all produce the same keycode on a Linux console.  But
there is a way to get at the state of the modifier keys (Shift, Ctrl,
Alt): ioctl(0, TIOCLINUX) so I have used that.  It breaks down when
keystrokes get queued, or when ssh'ing to another machine, but for
typical use on a local VT, it works fine.

<Left>, <Shift+Left>, <Ctrl+Left> on a Linux console:
Sequence of hex codes: 104
Sequence of hex codes: 104
Sequence of hex codes: 104

<Left>, <Shift+Left>, <Ctrl+Left> on an Xfce Terminal:
Sequence of hex codes: 104
Sequence of hex codes: 189
Sequence of hex codes: 221
