Noob questions

[securityinstruts]

So, few things that I noticed while building and testing new Mun lander;

In VAB: somehow managed not to be able to copy parts(fuel tanks). How to do this? I could select assemblies and use Ctrl+c and Ctrl+v but not shift+left click or similar easy and quick way to copy single parts.

In flight: Could not look down, could not rotate camera around the vehicle (side to side motion with mouse caused the view to rotate making up down and vice versa) and could not activate action groups (ladders, solar panels and communications that I had set to work as toggle deployment in action groups 9, 6 and 8).

I'm a noob but this feels silly.
What am I doing wrong?

There are multiple camera settings which you can switch between by hitting V. Maybe you were in a mode that didn't respond the way you were expecting?

Try alt+click.

This seems to be a bug. Action groups sporadically don't work, and there are other systems at play that can break action groups in novel ways. You might be able to fix it by saving and loading or  by reloading the vessel in some other way.
