The accelerator(s) represented by this object.
This property is used if [property@Gtk.ShortcutsShortcut:shortcut-type] is set to gtk_shortcut_accelerator .
The syntax of this property is (an extension of) the syntax understood by [func@Gtk.accelerator_parse]. Multiple accelerators can be specified by separating them with a space, but keep in mind that the available width is limited.
It is also possible to specify ranges of shortcuts, using `...` between the keys. Sequences of keys can be specified using a `+` or ` &` between the keys.
Examples:
Use "+" instead of "&" when the keys may (or have to be) pressed sequentially (e.g use "t+t" for 'press the t key twice').
Note that `<`, `>` and `&` need to be escaped as `<`, `>`; and `&`; when used in .ui files.
