<remark>
Some key combinations are used as global shortcut keys for a given widgetset
(QT, GTK, Cocoa), window manager (KDE, Gnome, Windows), or display protocol
(X11, Wayland, WinAPI). These global shortcuts are platform-specific and
generally perform system navigation or window management. They may be handled
by the desktop / window manager and not forwarded to an application, form, or
control. Some common examples include: Ctrl+F4, Alt+F4, Ctrl+Command+Q, and
others. For more details, please refer to the developer documentation for the
platform (widgetset) or desktop window manager.
