Bava Batra 65: Do You Get the Keys When You Buy the Door?

More on the dispute between Rabbi Akiva and the sages - who, with several cases. For example, what happens when a property is given to two different people, and neither has access to pass through the other's portion. Plus, the difference between a sale and a gift -- where the dispute whether a sale is "generous" does not apply to gifts, because it's accepted as a given that the gift with generosity. Also, a new mishnah! One who sells the door to one's home together with the house - but not the key to that door -- how does that work?! The Gemara then attempts to determine whether this mishnah is in accord with Rabbi Meir's approach or not.
