-If takes the same form as the other functions, expecting a new entities vector to be returned at the end. The first argument, `screen`, which we haven't talked about yet, is a Clojure map containing various important values. In the `:on-key-down` function, it will contain a `:keycode` which indicates what key was pressed. See the [documentation](http://oakes.github.io/play-clj/core.key-code.html) to for all the possible keys.

+To figure out what key it refers to, you'll need to compare it to a known key code, which you can get with `key-code`. See [the documentation](http://oakes.github.io/play-clj/core.key-code.html) or the example below to learn how to use it.
 
 Let's write a conditional statement that prints out which arrow key you pressed. Note that if a `defscreen` function returns `nil`, it leaves the entities vector unchanged, so the code below won't wipe out the entities vector.
