* GtkShortcutsShortcut:accelerator:

* The accelerator(s) represented by this object. This property is used

*
* The syntax of this property is (an extension of) the syntax understood by
* 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 + between the keys.
*
* Examples:
* - A single shortcut: <ctl><alt>delete
* - Two alternative shortcuts: <shift>a Home
* - A range of shortcuts: <alt>1...<alt>9
* - A sequence of key combinations: <ctl>c+<ctl>x
