RemappingFollow

Does anyone know how to remap the look settings on your mouse for FFXIV. Need help because I have been using the default keyboard settings but my "l" button is beginning to stick and I am a programmer on my laptop and can't have this. All I want to do is switch the look drag on the mouse from a right click to left click without switching anything else. Everything other than this good for me. Thanks to anyone who can provide the help I need.
