I find myself missing this constantly, and I am not even sure which version of Mac OS removed this.
Previously in App Expose (maybe regular Expose too?) once you Quick Looked a window you could just hit the arrow key left and right to see all the rest of the windows in Quick Look.
Now in App Expose you can highlight a window with the left/right keys but you have to enter/exit it with the space bar. It used to just switch from one Quick Look window to the next.
The current system makes less sense to me. If you have an Expose window open with Quick Look and then highlight another window with the arrow key and the press the space bar, it will Quick Look whichever window the cursor is over—not the currently highlighted one.
In short, the old system saved a lot of time, especially when I had tons of textedit documents open at a time.
