How to start programs that they are open but not run?

Dear Reader,
This is a simple question but to know the answer could help me.
When push the "apple" + TAB you see programs that not run and an other push on the tab change the frame on the program. If we push the "apple" + "Q" the program closing.
I like to know how can I start these programs that I see on this line.
What I do I close them and open again them klik on them but have to be a simple way to start them on shorter way.
Thanks for the anser.
