Access the File Inspector with Command-Option-i
You can access the File Inspector, a Quicklook style version of the Get Info command, by highlighting any file and then hitting the Command+Option+i keys, this is very useful because it allows you to select other files and pull up data about them upon click/selection rather than opening another Get Info window. This behaves very much like QuickLook, and the window will close if you select the desktop rather than an icon, or it loses the focus. Very useful, try it out!
Note: another way to access the File Inspector is by holding down the Option key and right-clicking on an icon, in place of “Get Info” will be “Show Inspector.”

This tip is soooo cool
Happy new year
i think just command+ i does it
In fact Cmd+I is enough…
What should be an interesting tip is the way to close all the File Inspectors when you have -by mistake- open many of them all together.
If you know the answer…
Cheers
Tom and Daniel, what you two are talking about are Get Info windows. The Inspector Window is different and I believe it is a holdover from the NeXT era. IIRC in the OS X beta releases, the Inspector was present but Get Info windows had yet to appear.
The diffrence is that you can have as many get info windows open at one time as you want. There is only one Inspector window and it’s contents change as you select different items in the finder.
Contrary to the article, the Inspector window does not close unless you tell it to by either clicking on the red close button or by pressing the usual window closing key combination, Cmd-W, when it is the active window. Even clicking the Desktop doesn’t make it close. Instead, it gives you information about the Desktop.
