# selectAll(_:)

Selects and highlights all cells in the receiver.

## Declaration

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

## Parameters

- `sender`: This argument is ignored.

## Discussion

Discussion Editable text cells and disabled cells are not selected. The receiver is redisplayed. If the selection mode is not NSMatrix.Mode.listModeMatrix, this method does nothing.
