this method is for connecting handlers to signals.

Keybindings in gtk are managed by objects called GtkAccelGroups. An
accel group contains mappings from (key,modifiers) combinations to
(object, signal) pairs. Accel groups are associated with toplevel
GtkWindows in a many-many relationship (so you can have accels that are
only valid in a particular window, and another group of accels that
apply to all windows, etc).
For gtk 1.2, accelerators can only be used to emit a signal on an
object. For 2.0, it is possible to simply connect a function to the key
combo. If you have handlers attached to the signals, then they will be
called when the key combination is pressed. Common signals to use are
"activate" (for menu items, this is equivalent to selecting them, for
entries the same as pressing enter), "clicked" (for buttons),
"grab_focus" (this will move focus to the given widget).
So your code might look something like:
accel_group = gtk.GtkAccelGroup()
window.add_accel_group(accel_group)
# as an example, make ctrl+e focus the widget "entry":
entry.add_accelerator("grab_focus", accel_group, 'e',
gtk.GDK.CONTROL_MASK, 0)
