This plugin lets you save your posts, pages, theme and plugin files, widgets, menus, etc. in the most natural way: pressing Ctrl+S (or Cmd+S on Mac).
I've coded this plugin because I was tired of pressing Cmd+S and then realize Chrome was trying to save the whole webpage
After coding this up, I've found in the plugin directory two plugins that did the same thing, but each one had some flaws that convinced me to publish mine.
This plugin loads a small Javascript file (minified if not WP_DEBUG). The Javascript checks the contents of any admin page for save buttons.
It is also so smart that saves as draft unpublished posts/pages and updates the ones that are already public.
Also adds a little tooltip on the buttons that can be "clicked" with Ctrl+S or Cmd+S.
