Question

how can i retrieve which one of my selection is my “current” target?
I would like to have different variables inside this function.

$('#header a, #nav a').click(function (event) {

// if is $('#header a')  do this
// if is $('#nav a')  do that   

});

this will refer to the actual DOM element, and so you can check tagName or className, or look for $(this).parents('#header').

$('#header a, #nav a').click(function (event) {
  var $this = $(this);

  if ($this.parents("#header").length > 0) {
    display("I'm inside #header");
  }
  else if ($this.parents("#nav").length > 0) {
    display("I'm inside #nav");
  }
  else {
    // Obviously this won't happen.
    // None of us has *ever* changed a selector and forgotten to update the code! ;-)
    display("I'm confused!");
  }

  return false;

});

Off-topic: I agree with Felix and melaos that if you’re really doing things that different, refactoring into separate handlers (perhaps calling common functions) is probably the better way to go…
