* The pager is an object that allows flipping (with animation) between 1 or
- * more ?\9cpages??of objects, much like a stack of windows within the window.
+ * more “pages” of objects, much like a stack of windows within the window.
*
- * Objects can be pushed or popped from he stack or deleted as normal.
+ * Objects can be pushed or popped from the stack or deleted as normal.
* Pushes and pops will animate (and a pop will delete the object once the
* animation is finished). Any object in the pager can be promoted to the top
* (from its current stacking position) as well. Objects are pushed to the
* needed and is not the top item, just delete it as normal. You can query
* which objects are the top and bottom with elm_pager_content_bottom_get()
* and elm_pager_content_top_get().
+ *
+ * Signals that you can add callbacks for are:
+ *
+ * "hide,finished" - when the previous page is hided
