Can you zoom out to see more in layout editor?

I'm working on large levels and, hey, this would be a problem with just about ANY size level in a game, but I need to be able to zoom out in the layer editor. It SHOULD be able to scale it, but can it? If it can't, then, well, it is absurdly inefficient for making any game with a decent sized layout. =/

You can hold down the control key and use the scroll wheel on your mouse to zoom.

and if you're on a laptop without mousewheel emulation, you're pretty much.... done for.

True story.
