Arch 5 - how did I turn this on??
 

I was typing in some text in Arch 5 and I guess I must have hit some keystrokes that turned on this great feature - all of my MENU TEXT now has arrows pointing to the direction that the menu items will go when I press - R L Up or DOWN. It looks like a mind map or web map on each item. I am hoping this doesn't go away when I turn the program off, it is a really nice feature.

Not sure about a keyboard shortcut but the command is
View - Workspace Overlays - Show Navigation Overlay.
