how to walk through values of an pull down menu?
in The Commons
Is it possible to simple walk through values of an pull down menu - eg the cams in viewport?
Usually I know cursor up/down (on pc) for that but it doesn't work.

Working fine for me:

Works for me as well. The pulldown stays open and you can either drag the mouse pointer or scroll with the arrow keys.
thank you for this videos.
& sorry for the misunderstanding - missing details.
I mean if you selected a cam in viewport & the viewport is actualized, I tried then cursor up/down (without open or clicking on menu).
From other software I know that you can walk through values in such way - like changing the last changed value. Or to move mouse over the closed menu and scroll through values by mousewheel (without open or clicking on menu).
Is there such a way?
I doubt it, but it's probably possible to write a script or plugin that can do this, either with its own menu or by modifying the existing ones.
