When in a contact record, when you hover over the activites tab, you can see the activities list.  I would like to make it so that when I hover over a particular activity, I can see the comment (description) of the activity.  

For example, If I am in a contact record, I can see that I spoke with the contact 3 times this week, but I cannot see what was discussed.  I would like to be able to see the content of the calls without having to leave the contact record.  

Can someone help me with this?
