Command + tab will do the same thing, otherwise, you can swipe up with three fingers to get something similar. It will show you all your open apps, and you can either click on one, or put your cursor over it and swipe down with three fingers. I believe you have to have this gesture turned on though which you can do from System Preferences > Trackpad. It is the 'mission control' gesture. It might not be exactly what you are looking for, but it works well for me, so I hope it helps you too.
