A Boolean that indicates whether pressing the Tab key advances the key cell to the next selectable cell.
- macOS 10.0+
When the value of this property is
true, pressing the Tab key should advance the key cell to the next selectable cell in the receiver. When the value of this property is
false or if there aren't any selectable cells after the current one, the next view in the window becomes key when the user presses the Tab key.
Pressing Shift-Tab causes the key cell to advance in the opposite direction (if the value of this property is
false, or if there aren’t any selectable cells before the current one, the previous view in the window becomes key).
