+ * Compares all values of two observables in sequence using an optional comparor function
+ * and returns an observable of a single boolean value representing whether or not the two sequences
+ * are equal.

+ *
+ * `sequenceEqual` subscribes to two observables and buffers incoming values from each observable. Whenever either
+ * observable emits a value, the value is buffered and the buffers are shifted and compared from the bottom
+ * up; If any value pair doesn't match, the returned observable will emit `false` and complete. If one of the
+ * observables completes, the operator will wait for the other observable to complete; If the other
+ * observable emits before completing, the returned observable will emit `false` and complete. If one observable never
+ * completes or emits after the other complets, the returned observable will never complete.
+ *

+ *  "ArrowLeft",

+ *  "KeyB",
+ *  "KeyA",
+ *  "Enter" // no start key, clearly.
