Widget.addAccelerator

void addAccelerator(string accelSignal,  gtk.accel_group.AccelGroup accelGroup,  uint  accelKey,  gdk.types.ModifierType accelMods,  gtk.types.AccelFlags accelFlags)

Installs an accelerator for this widget in accel_group that causes accel_signal to be emitted if the accelerator is activated. The accel_group needs to be added to the widget’s toplevel via [gtk.window.Window.addAccelGroup], and the signal must be of type G_SIGNAL_ACTION. Accelerators added through this function are not user changeable during runtime. If you want to support accelerators that can be changed by the user, use [gtk.accel_map.AccelMap.addEntry] and [gtk.widget.Widget.setAccelPath] or [gtk.menu_item.MenuItem.setAccelPath] instead.

Parameters

`accelSignal`	widget signal to emit on accelerator activation
`accelGroup`	accel group for this widget, added to its toplevel
`accelKey`	GDK keyval of the accelerator
`accelMods`	modifier key combination of the accelerator
`accelFlags`	flag accelerators, e.g. [gtk.types.AccelFlags.Visible]
