How can I set my Galaxy S5 home button double click to show all opened apps?

[AC Question]

There is a capacitive button that does it (the one with two squares), but I want to disable those touch buttons since I keep accidentally clicking on them while playing games. I want to use only the mechanical home button, one click to go to home screen, double click to show all opened applications.

Hello, I have a s5 and I haven't found out with samsung launcher (touchwiz) however with alternative launcher you can program any button or swipe gesture for anything. I used Apex Launcher on my S3, it is worth trying it on your phone.
