Can you get a list of the RUNNING applications on Android for the purpose of activating them?

On my Samsung Galaxy S Android phone: if I start a couple of apps, I can get an overview of them in the 'Active applications' icon on my first screen. Clicking this icon, shows me all active applications but allows me only to end them. I find no way to activate them. Pressing the center touchpath at the bottom displays the last 6 clicked icons - which may or may not be the ones running. F.i. if I start 6 applications, I see these 6 icons, if I start a 7th one I see the last 6 started. I wont see the first icon again . So how can I activate this first one, other than knowing it is running, and tapping it's icon again ? Please don't start telling me why I should start 6 or more applications. That's not the point, here , of course :) ANSWER: **You can't** - at least not by using the system as it is installed. A well, no big deal, really. Just wanted to see if I was missing something here. Coming from a Windows background (*and aren't we all because otherwise we should be holding an iPhone now*), this did not seem to illogical. Thanks for all answers.
