Help Back in one time

[spaansebraband]

If I visit 10 pages of Teletex or whatever on smartphone or tablet, and I want to stop, I have to switch back 10 times untill the app asks me wheter I want to stop. Is it possible that I stop after looking say 10 pages by pressing one button?

The HOME button will always work. The app will still be running in the background, but Android doesn't seem to care.
