If you have been following my blog for a while you know that I’m a big fan of Alfred. I use it all the time for finding and opening files. One thing I didn’t know though is that when searching files you can do a Quick View. In the past, I’ve always opened the file in the appropriate app to view it. With Alfred Quick View I can press ⇧ or ⌘Y to bring up a quick view of the file. This is a nice time saver.
