On Mac OS X, there is a handy key combo for taking a screenshot of any arbitrary rectangle section of the screen(Command-Shift-4).
Is there something similar(maybe Compiz plugin) for Ubuntu/Gnome?

Shutter is a good screenshot tool that has this feature, among others.
Press shift + printScr and then a click drag to select the area you want a screen shot of
It is possible that the key combination shift+PrntScreen may not be the short cut to do this, then -
Command line interface way( i.e through terminal)(you need dconf-editor for this) -
gsettings get org.gnome.settings-daemon.plugins.media-keys area-screenshotto get the key combination currently assigned to get a screen shot of an area.
gsettings set org.gnome.settings-daemon.plugins.media-keys area-screenshot "[<Shift>Print']"Simly replace
"[<Shift>Print']"with your desired key combination.
Note: I have tried this method on Ubuntu 13.04, and I remember using it on Ubuntu 12.10. I know very little about the possibility of using these ways in Ubuntu versions before that..
Now, I you hit the shortcut, the cursor changes to a big +. Select an area, and the screenshot is saved to the clipboard.
