Window Switching in Ubuntu

In both Windows and Ubuntu Linux you can switch active windows by pressing control (ctl) and tab. However on Windows if you press ctl-alt after pressing ctl-tab the previously active window will stay in the foreground. I find this very useful so it really bugs me that I haven't found a way to do this in Ubuntu. I've had a look at the keyboard mappings for window switching and there isn't a space for reverting to the previously active window. If anyone knows how to do this please let me know!

Car Names

Who gets paid to give cars their names? Where do they come up with such ridiculous names?

I mean take "Charade"... I can just see two people talking:

Person 1: What sort of car do you have?
Person 2: Car? It's a "Charade".
Person 1: So you don't have a car? It's a sham?
Person 2: No it's a "Charade".
Person 1: That's what I said.
...

I can see an almost identical conversation with the "Mirage". What kind of stupid name is that? Why do you want a car that's a charade or a mirage?

One of my other favorites is the "Prelude". Prelude to what? I think I'll wait for the real thing thanks.
