let's have $tg a Tk::TixGrid object,and let's consider <Button-1> and <B1-Motion> two constants wich are indicating to events produced by mouce clicks and ShowCell the subrotuine run at those certain events.What does Ev mean in this context ? In the source I have these 2 lines are used.And Ev is never defined nowhere in the source.I can also assure that they are not defined in any other modules included in there. 

$tg->bind('<Button-1>',  [\&ShowCell, Ev('x'), Ev('y')]);
$tg->bind('<B1-Motion>', [\&ShowCell, Ev('x'), Ev('y')]);
