Another Quicksilver Trick
Ultra useful time saver!
Select an item in the Finder, invoke Quicksilver, then choose an application or a location in the file system; then hit Alt (option), Command and G.
Now, if you chose an application in QS, it will be ready for you to open the file with the chosen application; if you chose a location, it will be ready for you to move the file to that location.
It sounds complicated, but once you‘ve done it a few times, you’ll find your self using it more and more!
SteamSHIFT out.
