You have the key name wrong (the example is not in C but anyway):


Gtk::Accelerator.to_name *(Gtk::Accelerator.parse "<ctrl>esc")
=> "<Control>"

Gtk::Accelerator.to_name *(Gtk::Accelerator.parse "<ctrl>Escape")
=> "<Control>Escape"

Gtk::Accelerator.parse "<ctrl>Escape"
=> [65307, #<Gdk::Window::ModifierType control-mask>]
