Today in class, we discovered a new Kindle feature.  The students were discussing the question:  What does the Chorus say about what makes love desirable or not desirable? (in Medea)

In order to find this in the text, students were able to type in the key word "love."  Every time the word love was used, the text appeared in the form of a list.  Students were able to locate the place in the text, click on the reference, and it took them to the page. 
This is just another fantastic feature about the Kindle-it gives students the ability to find things faster within the text, vs. flipping back (or tapping back on the touch screen).  Below is how the page appeared (as an example from the Amazon website):
