Admin Quick Jump is a very simple plugin that adds a dropdown list to the admin edit-post area. The list contains posts of the same post_type as the one you are currently editing, and allows you to quickly jump between other draft and published posts. This is much less time-consuming than navigating back to the posts list and choosing the post you need. Perfect for quickly jumping between editing posts, pages and custom posts. No plugin settings page required, simply install and activate the plugin.
