Value | Symbolic name | Description | 
|   0 | GTK_ACCEL_VISIBLE | 
   Denotes that the accelerator key along with any associated modifiers 
   should be displayed to the right of any text in a 
   GtkAccelLabel.  Note that this will always be
   displayed as upper case, whereas a lower case key value is actually
   being returned.  Use a shift modifier if this is likely to cause a
   problem for your users.  (See also: GdkModifierTypes.)
   | 
|   1 | GTK_ACCEL_SIGNAL_VISIBLE | 
   This flag does not work, and has been eliminated completely in later
   versions of GTK+.  Use GTK_ACCEL_MASK to achieve
   the desired effect.
   | 
|   2 | GTK_ACCEL_LOCKED | 
   Denotes that the accelerator entry is locked.  However, this does not seem
   to work everywhere in the current version of GTK+.  Call the GtkWidget
   method lock_accelerators()  on the
   target widget - usually a GtkMenuItem - in order
   to ensure accelerator entry locking.
   | 
|   3 | GTK_ACCEL_MASK | 
   Returns full information for a GtkAccelGroupEntry (the individual element
   in a GtkAccelGroup array), displaying any
   modifiers,  the accelerator key and the name of the associated signal to
   the right of any existing GtkAccelLabel text.
