Single lettered function names in jquery/json?

Single lettered function names in jquery/json?

Can someone please explain what this code does. The thing that I found
most irritating about this function is its single-lettered name. How can i
know what is the purpose of this function and what invokes this funciton.
function i() {
$(".main_section").delegate(".saveExam", "click", function () {
ename = $("#addmore").val();
$.ajax({
url: "saveNewExam.php",
type: "POST",
data: {
examId: ename
},
dataType: "html",
success: function (e) {}
});
window.location.reload()
})
}
