I used this tip top hide my menu bar in a bunch of applications, which is a great way to get more free screen space. The one downside is that (for inexplicable reasons) it disables Spotlight when I'm in those applications--e.g. even if I hover over the menu bar to make it appear, clicking on the Spotlight icon does nothing.

I have a plan to work around this: I'd like to launch Spotlight using QuicKeys, which lets you run terminal commands using keyboard shortcuts. But to do that, I need to know how to launch Spotlight with a terminal command. Does anyone know how to do this?

I'm on OS X 10.6.
