I always used keystroke navigation to transverse the CIA browser menu. Anyone else ever had the thought of adding the following Facepanel shortcuts.
[shift] + [page right] = total expand of hierarchal menu
[shift] + [page left] = close all menus and exit to top of menu list
[shift] + [page left] + [page right] = close all hierarchal menus except the current menu you are in
[shift] + [page down] = drop down to next primary group heading
[shift] + [page up] = spring up to next primary group
[shift] + [page up] + [page down] = spring to top entry point of menu list
I know this completes with the facepanel shortcuts that perform column moves and resizes but the above combinations would only be active when the CIA is open and being active.
