Microsoft Sculpt Ergonomic Keyboard

I recently purchased the Microsoft Sculpt Ergonomic keyboard for use with my MacBook Pro (Retina, 15-inch, Mid 2014) running OSX Yosemite v10.10.1. I love the feel of the keyboard and would like to use it successfully for all of my business needs; however, the key mappings are far from perfect and I'm looking for a way to map F-keys, and certain key combinations to work more like a Windows machine.

I should mention I'm brand new to the iOS world for my business platform. While I've used iOS on my phone and tablet for years, a recent change in employment has brought me over to a full Mac shop for my "desktop" experience.

My reviews have suggested some modifications to the "DefaultKeyBinding.dict" file using TERMINAL... but I was hoping for a more elegant or graphically-friendly solution. I also tried to download a driver pack from www.microsoft.com but my machine stated that it couldn't' be installed because it wasn't downloaded form the Apple App Store.

I hope someone in this community can point me in the right direction.
