Hi,
in the following file are all the keycodes 
'include/gtk-2.0/gdk/gdkkeysyms.h' to see what key is pressed create a 
signal handler and connect it like this:

bool classname::key_press(GdkEventKey *key)
{
   if(key->keyval == GDK_a)
       //do something when 'a' is pressed 
}

connect it for example to a window:
window.signal_key_press_event().connect(sigc::mem_fun(*this, 
&classname::key_press));

Hope this made it a bit clearer,
