key bindings

[Jaap Karssenberg <j g karssenberg student utwente nl>]

I would like to add custom key bindings to a widget, preferably binding
keys directly to perl subroutines. Now I found in the Gtk reference this
page <http://developer.gnome.org/doc/API/2.0/gtk/gtk-Bindings.html> but
this is totally unhelpful due to the lack of descriptions/explanations.
Could someone show me how to bind a key to a perl sub ?
