 Fundamentally, cursors are based on [lenses](https://speakerdeck.com/markhibberd/lens-from-the-ground-up-in-clojure). That means that you can pass any arbitrary getter (of the form `(fn [parent-state])`) and setter (of the form `(fn [parent-state cursor-state])`) and the cursor will handle it.

 cursors can also be created by passing in a keyword or a key sequence that would be passed to `get-in` or `assoc-in` to the `cursor` function:
 
 ```clojure
-(def my-atom (atom {:a {:b [{:x 0}]}))
-(def ab0 (cursor my-atom [:a :b 0]) ;; -> {:x 0}
+(def my-atom (atom {:a {:b [{:x 0}]}}))

 (def a (cursor my-atom :a) ;; a keyword can be used as well
