Capturing a window image or taking a screen shot in a Windows XP virtual machine running in Virtual Box on a MacBook pro?

I've got a MacBookPro (no external keyboard, just the built-in laptop keyboard) and I'm running Virtual Box. My virtual machine is Windows XP and I'd like to capture an image of a window (or the whole screen if that's easier). It's not obvious to me how to express Alt-PrtScr` to the Windows XP VM with my MacBook Pro keyboard. I have Virtual Box Guest Additions installed.

Solution 1:

Virtualbox has a capture functionality.

Use the menu Machine -> Take screenshot

Or the shortcut Cmd+e

Solution 2:

Some versions of VirtualBox don't have the menu for taking a screenshot but the combination of shortkeys will work. Try Command key and E together and a menu will pop to get the name and address for saving the screenshot file.

Hope it helps.
