Back and forward navigation arrow icon gone

Question

There used to be two little blue back and forwards navigation arrow icons in the Android Studio toolbar that provided navigation between recent source files I was editing. Now, for some reason, this little navigation arrow is gone. Any idea how to get it back or what it's called? Thanks!

Found the answer

For some reason the toolbar is not visible by default. In the View menu, select Toolbar. That should fix it.
