Question regarding keyboard configuration

Hey guys,

I am trying to set up my keyboard for mac, in a way that the Home/End keys act like they do on my Linux box (move the cursor to beginning/end of line). For MAC, I downloaded Karabiner which maps the keyboard keys to the intended configuration, however, as soon as I start Karabiner, then the Intellij keymap is messed up. Has any one of you tried doing it? Can you please help me?

Thanks in advance! :)
