Ethan Atkins 81ce14d58c Allow calling TaskKey.previous in input tasks ... I discovered that it wasn't possible to call .previous in an input task. While I understand why you can't call .previous on an InputKey, I think it makes sense to allow calling .previous on a TaskKey within an input task.		2019-04-25 15:58:01 -07:00
