Xcode 4 Keyboard Shortcuts (cocoasamurai.blogspot.com)

Going to ask these two questions here:

1. Is it not possible to show column position indicators on the toolbar anymore?

2. What happened to the Quick Look plugin (was in XCode 3.2) that shows colour syntax highlighting on previewed files in Snow Leopard? Any way to get this plugin back?

Since a thread has started, I've not been able to find it yet, but is there behavior that is similar to Visual Studio's ctrl-tab? I like being able to quickly switch between recent files, and I find the back/forward functionality in Xcode 4 to be frustrating, in that I will often 'lose' files in the chain by jumping back, and then searching for something else.
