## ol/interaction/KeyboardPan~KeyboardPan

    import KeyboardPan from 'ol/interaction/KeyboardPan.js';

Allows the user to pan the map using keyboard arrows. Note that, although this interaction is by default included in maps, the keys can only be used when browser focus is on the element to which the keyboard events are attached. By default, this is the map div, though you can change this with the `keyboardEventTarget` in `Map`. `document` never loses focus but, for any other element, focus will have to be on, and returned to, this element if the keys are to function. See also `KeyboardZoom`.

#### new KeyboardPan(options)

interaction/KeyboardPan.js, line 35

  Name | Type | Description
  --- | --- | ---
  `condition` | Condition | undefined | A function that takes a `MapBrowserEvent` and returns a boolean to indicate whether that event should be handled. Default is `noModifierKeys` and `targetNotEditable`.
  `duration` | number (defaults to 100) | Animation duration in milliseconds.
  `pixelDelta` | number (defaults to 128) | The amount of pixels to pan on each key press.

  ##### Fires:

  - `change` (BaseEvent) - Generic change event. Triggered when the revision counter is increased.
  - `change:active` (ObjectEvent)
  - `error` (BaseEvent) - Generic error event. Triggered when an error occurs.
  - `propertychange` (ObjectEvent) - Triggered when a property is changed.

Object.js, line 136

  Gets a value.

  Name | Type | Description
  --- | --- | ---
  `key` | string | Key name.

  ##### Returns:

  Value.

#### getActive(){boolean} inherited

interaction/Interaction.js, line 82

  Return whether the interaction is currently active.

  ##### Returns:

  `true` if the interaction is active, `false` otherwise.

#### getKeys(){Array.<string>} inherited

Object.js, line 149

  Get a list of object property names.

  ##### Returns:

  Map.

#### getProperties(){NoInfer.<Properties>} inherited

  ##### Returns:

  Revision.

#### on(type, listener){EventsKey | Array<EventsKey>} inherited

Observable.js, line 152

  Listen for a certain type of event.

  ##### Returns:

  Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.

#### once(type, listener){EventsKey | Array<EventsKey>} inherited

Observable.js, line 164

  Listen once for a certain type of event.

  Name | Type | Description
  --- | --- | ---
  `type` | string | Array.<string> | The event type or array of event types.
  `listener` | function | The listener function.

  ##### Returns:

  Unique key for the listener. If called with an array of event types as the first argument, the return will be an array of keys.

#### set(key, value, silent) inherited

Object.js, line 218

  Sets a value.

  Name | Type | Description
  --- | --- | ---
  `key` | string | Key name.
