    Assuming that by ‘next/previous’, you mean ‘the entity with the key that is lexicographically closest to a given key’, yes, you can do this using queries. Supposing your key is in ‘my_key’, and your model is called MyModel, in Python it would work like this:

    q = MyModel.all().filter('__key__ >', my_key)
next_entity = q.get()

q = MyModel.all().filter('__key__ <', my_key)
prev_entity = q.get()
