Is it possible to run commands from spotlight?
Just a heads up that Alfred app now has both global hotkeys which allows you to launch apps/commands/applescripts with a key combo, as well as Terminal/Shell integration, which lets you run any Terminal command without launching Terminal.

For example, create a script to auto-shorten a URL using goo.gl then copying it to clipboard (here's how you can do that). Or launch any terminal command (e.g. ping yahoo.com) to pop up a Terminal window.

It's part of the Powerpack and is in pre-release right now, going to general availability next week :)
