IntelliJ Navigation Bar Hot Key

Question

IntelliJ 15 says that the hot key is ⌥↖︎ to open the Navigation Bar, but how do you do this?

I assumed that it was option+↑+← but that doesn't seem to do anything in IntelliJ.

Answer 1

Oh just playing around with it a little more, I had to include the fn key.

So it's fn+option+↑+← if anyone else was trying to figure this out.
