Swipe to reveal toolbar in Go?

[Wickerman]

Hi -- I have a few iPad solutions I created awhile back, where I hid the upper and lower toolbars from view.  but as I recall, there was a swing gesture I could use to reveal them -- I thought it was swiping down with 3 fingers . . . but this seems no longer to work?  

Can someone jog my memory on this?  I just need to be able to reveal the "Find" function temporarily.
