KeyboardShortcuts Edit

<KeyboardShortcuts /> is a component which handles keyboard sequences during the lifetime of the rendering element.

When passed children, it will capture key events which occur on or within the children. If no children are passed, events are captured on the document.

It uses the Mousetrap library to implement keyboard sequence bindings.

Example Example

Render <KeyboardShortcuts /> with a shortcuts prop object:

import { KeyboardShortcuts } from '@wordpress/components';
import { withState } from '@wordpress/compose';

const MyKeyboardShortcuts = withState( {
    isAllSelected: false,
} )( ( { isAllSelected, setState } ) => { 
    const selectAll = () => {
        setState( { isAllSelected: true } )
    };

    return (
        <div>
            <KeyboardShortcuts shortcuts={ {
                'mod+a': selectAll,
            } } />
            [cmd/ctrl + A] Combination pressed? { isAllSelected ? 'Yes' : 'No' }
        </div>
    ) 
} )

Props Props

The component accepts the following props:

children children

Elements to render, upon whom key events are to be monitored.

  • Type: Element | Element[]
  • Required: No

shortcuts shortcuts

An object of shortcut bindings, where each key is a keyboard combination, the value of which is the callback to be invoked when the key combination is pressed.

  • Type: Object
  • Required: No

Note: The value of each shortcut should be a consistent function reference, not an anonymous function. Otherwise, the callback will not be correctly unbound when the component unmounts.

Note: The KeyboardShortcuts component will not update to reflect a changed shortcuts prop. If you need to change shortcuts, mount a separate KeyboardShortcuts element, which can be achieved by assigning a unique key prop.

bindGlobal bindGlobal

By default, a callback will not be invoked if the key combination occurs in an editable field. Pass bindGlobal as true if the key events should be observed globally, including within editable fields.

  • Type: Boolean
  • Required: No

Tip: If you need some but not all keyboard events to be observed globally, simply render two distinct KeyboardShortcuts elements, one with and one without the bindGlobal prop.

event event

By default, a callback is invoked in response to the keydown event. To override this, pass event with the name of a specific keyboard event.

  • Type: String
  • Required: No
