QML Shortcut documentation is short...

For example, it doesn't explain we can create several shortcuts with the same sequence and enable one, like for a radio button.

Basic example to test this feature:

    Shortcut {
        id: shortcut1
        sequence: StandardKey.MoveToPreviousPage
        enabled: true
        onActivated: {
            console.info('shortcut1')
            enabled = false
            shortcut2.enabled = true
        }
    }

    Shortcut {
        id: shortcut2
        sequence: StandardKey.MoveToPreviousPage
        enabled: false
        onActivated: {
            console.info('shortcut2')
            enabled = false
            shortcut1.enabled = true
        }
    }

To explore use cases, we can give a look to the sophisticated Emacs key maps:

• https://www.gnu.org/software/emacs/manual/html_node/emacs/Keymaps.html
• https://www.gnu.org/software/emacs/manual/html_node/elisp/Keymaps.html

Which implements modes and an active keymap, which is a merge of the global and locales keymaps.

A basic use case is to share a shortcut for several actions depending on the current application mode. Then the question is how we should implement the mapping ?

Further info

QML Shortcut is implemented in

• qtdeclarative/src/quick/util/qquickshortcut.cpp
• qtbase/src/gui/kernel/qshortcutmap.cpp

Shorcuts are stored in QGuiApplication

QGuiApplicationPrivate *pApp = QGuiApplicationPrivate::instance();
shortcut.id = pApp->shortcutMap.addShortcut(this, shortcut.keySequence, context, *ctxMatcher());
