You say that F6 key brings up the Operator Panel but this doesn't work in 2.78.5. What is the equivalent key in the latest version of Blender? Thanks

Thanks Jonathan.  I'm actually on a PC but the Fn thing is the same.

All working fine.

i got windows Dell laptop and its also Fn + F6,  F6 alone  gives a message " no more keyframes to jump in this direction" .

I encounter a similar problem on my laptop.
It turns out that since my FnLk key  (Function Lock)  was set (green light showing in order to lock the F# keys so I don't have to use the Fn+F#), then my F6 didn't work.
I turned off the FnLk and now my F6 is working properly and I can use the operator menu.
Hope it helps

Beginner question: is the operator panel the same as the last operator panel? F6 for me keeps bringing up a popup menu with one item: delete, not an operator panel. The trouble with all these panes, regions, or panels is that hovering over them does not reveal their title, so a beginner can't tell what is what.
