I've been trying to take screenshots of Chromium's Google search suggestions as I type. I would also like to include Google's instant search results.
I tried using the Print Screen key, and also Ubuntu's 12.04 gnome-screenshot utility.
The issue is that when I press PrtScr, focus is off Chromium's window, which causes it to automatically abort the search, and show the webpage that was on the screen when I started typing a new search.
You can see in the screenshot below, that I typed www.askub, and Google's search suggestion was www.askubuntu, among other suggestions. An instant search result appeared that included this site as the first hit. But none of these things are in the screenshot.
