Yes,  can read the documentation.

And it does not answer my question *when* this is called. It only says =
what it's supposed to do *after* it's called.=20

And what it may suggests, namely that it is called after a mouseDown, is =
not what is actually true in practice. Neither in NSTextField nor in =
NSTableView is it called after a mouseDown.=20

So my question still remiains: when is this ever used?
