 The rest of the traversal methods within jQuery all deal with finding sibling selections. There are a few basic methods as far as the direction of traversal is concerned. You can find previous elements with `$.fn.prev()`, next elements with `$.fn.next()`, and both with `$.fn.siblings()`. There are also a few other methods that build onto these basic methods: `$.fn.nextAll()`, `$.fn.nextUntil()`, `$.fn.prevAll()` and `$.fn.prevUntil()`.
