 ### States
 
-If you set ``data-state="someState"`` on a slide ``<section>``, "someState" will be applied as a class on the document element when that slide is opened. This allows you to apply broad style changes to the page based on the active slide.
+If you set ``data-state="somestate"`` on a slide ``<section>``, "somestate" will be applied as a class on the document element when that slide is opened. This allows you to apply broad style changes to the page based on the active slide.
 
 Furthermore you can also listen to these changes in state via JavaScript:
 
 ```
-document.addEventListener( 'someState', function() {
+Reveal.addEventListener( 'somestate', function() {
        // TODO: Sprinkle magic
 }, false );
 ```
 
+### Slide change event
+
+An 'slidechanged' event is fired each time the slide is changed (regardless of state). The event object holds the index of the current slide.
+
+```
+Reveal.addEventListener( 'slidechanged', function( event ) {
+       // event.indexh & event.indexv
+} );
+```
