ShortcutAction

`GtkShortcutAction` encodes an action that can be triggered by a keyboard shortcut.

`GtkShortcutActions` contain functions that allow easy presentation to end users as well as being printed for debugging.

All `GtkShortcutActions` are immutable, you can only specify their properties during construction. If you want to change a action, you have to replace it with a new one. If you need to pass arguments to an action, these are specified by the higher-level `GtkShortcut` object.

To activate a `GtkShortcutAction` manually, [[email protected]] can be called.

GTK provides various actions:

• [[email protected]]: a shortcut action that calls mnemonic_activate
• [[email protected]]: a shortcut action that invokes a given callback
• [[email protected]]: a shortcut action that emits a given signal
• [[email protected]]: a shortcut action that calls activate
• [[email protected]]: a shortcut action that calls activate_action
• [[email protected]]: a shortcut action that does nothing
