 GTK has traditionally supported different kinds of shortcuts:
 
-Accelerators
- : Accelerators are any other shortcuts that can be activated regardless
-   of where the focus is, and typically trigger global actions, such as
-   Ctrl-Q to quit an application.
-Mnmemonics
- : Mnemonics are usually triggered using Alt as a modifier for a letter.
-   They are used in places where a label is associated with a control,
-   and are indicated by underlining the letter in the label. As a special
-   case, inside menus (i.e. inside #GtkPopoverMenu), mnemonics can be
-   triggered without the modifier.
-Key bindings
- : Key bindings are specific to individual widgets, such as Ctrl-C or
-   Ctrl-V in an entry copy to or paste from the clipboard. They are only
-   triggered when the widget has focus.

 capture phase, and key bindings locally, during the target phase.
