KEY_SHORTCUTS
Description:
Indicates keyboard shortcuts that an author has implemented to activate or give focus to an element.
Value type: string. The format of the value is a space-separated list of shortcuts, with each shortcut consisting of one or more modifiers (
`Control`, `Alt` or `Shift`), followed by a non-modifier key, all separated by `+`. The [WAI-ARIA](https://www.w3.org/TR/wai-aria/aria
-keyshortcuts) reference specifies how to build keyboard shortcuts strings, with specific values for each key which are the same
regardless of the language, so these strings can't be built from localized key names. You can convert an accelerator into the matching key
shortcuts label with [func@Gtk.accelerator_get_accessible_label]. Examples: `F2`, `Alt+F`, `Control+Shift+N`
