How to change Home / End behaviour on Yosemite

I want to change Home / Keys to work like Windows/Linux.

Home to Cmd+Left Arrow. //not control+A

End to Cmd+Right Arrow. //not control+E

I tried using Karabiner app known as KeyRemap4MacBook. But it doesn't work while i write code on editors. It works on browser but useless for me.

I also did. Create a DefaultKeyBindings.dict file (with proper settings) inside ~/Library/KeyBindings/ . There was not a folder name KeyBindings on Yosemite.

So, is there a way to remap Home/End buttons. This is sucking my energy, and takes a lot of time. I am about to smash my mac.
