[jQuery] keypress event using $(this)

[hubbs]

I have a simple keypress event that throws an alert when you press "a"
or "s".  Is it possible to bind this event to specific elements, so
that it is not a global keypress, but only fired if the test link is
first clicked.  Then, $(this) would be used to get attributes of the
clicked element if needed.

Any ideas on how to get that to work, or if it is possible?

$("#test").keypress(function(e)
        {
                switch(e.which)
                {
                        case 97:        alert("A pushed!");
                                                break;

                        // user presses the "s" key
                        case 115:       alert("S pushed!")
                }
        });
