Switch back and multitasking buttons - root required

A little tip for the ones who hold the phone in their left hand and need to switch the .back button with the multitasking one. I am right handed but, as a long time user of Note series phones, I usually hold the phone in my left hand and the stylus with the right one...Now with the s7 edge I miss the stylus, but still the phone is in my left hand.
Root required..
With your favourite root browser navigate to /system/usr/keylayout and open Generic.kl as a text file.
Move to key 158 and replace BACK with APP_SWITCH, then look for APP_SWITCH , that is key 254, and replace APP_SWITCH with BACK.
Just save and reboot.
Obviously it is fully reversible.
Please note that this is not the same result you can get with all in one gestures app, both because it continuously runs in the background (while my tip remaps the keys once forever) and, once you switch the two keys with such app, you loose the screen you usually get when you long press the multitasking button. I mean the screen that displays the app you are using in the upper part of the screen and the choice for the other apps in the lower part.
Not to mention that this solution still is cleaner than installing xposed framework and any dedicated module.
Simple and useful:)
If your rom settings don't have the choice to remove keys backlight, look for galaxy button lights 2.
