I have already read this web page http://api.jquery.com/end/ but I am still clueless on what .end() actually does. What is it for and how do you use it?

The following functions can be used to alter your jQuery selection, typically to make your selection more specific, or inclusive/exclusive:
add, andSelf, children, filter, find, map, next, nextAll, not, parent, parents, prev, prevAll, siblings, slice, clone, appendTo, prependTo, insertBefore, insertAfter, or replaceAll
.end() can be used to reset your selection back to your original set of elements, after having done some manipulation on the extended selection.
