# selectAll(_:)

Selects and highlights all cells in the receiver.

```
func selectAll(_ sender: Any?)
```

## Parameters

`sender`

This argument is ignored.

## Discussion

Editable text cells and disabled cells are not selected. The receiver is redisplayed.

If the selection mode is not [`NSMatrix.Mode.listModeMatrix`](/documentation/AppKit/NSMatrix/Mode-swift.enum/listModeMatrix), this method does nothing.

## See Also

[`selectCell(_:)`](/documentation/AppKit/NSControl/selectCell(_:))

Selects the specified cell and redraws the control as needed.
