Being a web designer I like to think that I live on two sides of each certain file; the viewing side and the editing side. What ends up happening to many web designers is they have more than one app that they typically use to open, view or edit a file, depending on the task they need to perform at the moment.
There is often a problem with that. Double clicking or command+O on a file opens it in it’s default app. Right+clicking or control+clicking the file to open the contextual menu then “open with” can be a pain (and slow) depending on the number of apps you run on your system. Opening the app and then browsing through the “Open file” function is too much like work. And finally, dragging the app onto a desktop icon is open useful if you keep everything you ever use in you dock at all times (which I don’t).
So in my ever lasting pursuit of the fastest way around these little hold-ups, I have come to rely on [QuickSilver](http://www.blacktree.com “Blacktree”) to, once again, saves the day. I use quicksilver to quickly and painlessly open any file with any app I choose and it all takes a few keystrokes and a few seconds:
1. Find the file you want to open, like an image (which, for me, opens with Photoshop by default),
2. Invoke [QuickSilver](http://www.blacktree.com/ “Blacktree”) (command+space in most cases, command+esc for me),
3. Start typing the name of the app you want to open your file with, like Preview.app for instance,
4. Once you app pops up in the first panel (with 2 or 3 keystrokes), simply drag your file onto the pane (like you would onto a dock icon),
5. POOF! The file opens in the app you want and not the files default app.
