I work a lot with virtual copies (the before-after function is a bit clumsy, and not so good for exploring different interpretations of an image).

There are keyboard shortcuts for so many things, but not for "create a virtual copy".

Or is there, and it just wasn't in the book?

If there isn't, is there a function, where you can create your own shortcuts?

The shortcut is Ctrl-' (Windows) or Cmd-' (Mac)

You can't currently create your own shortcuts - hopefully a future version.

Thanks, Victoria!

Is there any location where you find all the shortcuts listed, so you can print them out?

Follow the link at the bottom of her post.

thanks victoria!
i've stumbled across many of them but this is a good reference for seeing them all at once!
