I assume that you DON'T want to know when the user selects the textfield /using the mouse/, as that's almost always the wrong thing to do: there are many more ways to select a text field, and almost always, when you condition something on /how/ something happens rather than /what/ happens you're doing it wrong. 

So if you want to know when a text field gets selected (rather than when editing starts), I think you can only do that by subclassing NSTextFieldCell and overriding the appropriately named method.
