/// Global shortcut implemented with [hyprland_global_shortcuts_v1].
///
/// You can use this within hyprland as a global shortcut:
/// ```
/// bind = <modifiers>, <key>, global, <appid>:<name>
/// ```
/// See [the wiki] for details.
///
/// > [!WARNING] The shortcuts protocol does not allow duplicate appid + name pairs.
/// > Within a single instance of quickshell this is handled internally, and both
/// > users will be notified, but multiple instances of quickshell or XDPH may collide.
/// >
/// > If that happens, whichever client that tries to register the shortcuts last will crash.
///
/// > [!INFO] This type does *not* use the xdg-desktop-portal global shortcuts protocol,
/// > as it is not fully functional without flatpak and would cause a considerably worse
/// > user experience from other limitations. It will only work with Hyprland.
/// > Note that, as this type bypasses xdg-desktop-portal, XDPH is not required.
