Note 2 back / home button

Hello everyone:

I have a Note 2 with the back light.

On the Note + I could hold down the back button to go home -- IE straight to the home page and start another app.

On the note 2, this turns on the back light,

Is there anyway on the Note 2 to go straight to the home page ?
Otherwise it's back, back, back through an entire app to go to the home page..

Thanks,
Michael
