I recently bought a CM Storm QuickFire keyboard. This keyboard is made for Windows. It works perfectly on Bootcamp, but when I use it on the OS X side, the keys are completely remapped.
the F key acts like F + down arrow
etc.
Does anyone know how to fix this? Or how to completely remap a keyboard?
Extra info:
I used an identical keyboard on a work computer (Mac) and it worked well. Any ideas why that would be?
I would try a Genius Bar at a local mac store if you are located near one. I have seen them fix some weird s/w issues right there.
Almost all of the keyboard shortcuts you've learned on Windows are the same on the Mac. The difference is which modifier key you use to invoke them.
On Windows, shortcuts are typically invoked with the Ctrl modifier key.
On the Mac, you use the 
key, also known as the "command" key. It's in the same physical position as the Alt key on a Windows keyboard, but is nothing like the Alt key.
The Mac has its own Alt key, labeled Opt/Alt. Its primary use is a secondary modifier for keystrokes. Command-Option-S might be "Save As", for example, while Command-S is regular "Save".
The Ctrl key is there on a Mac keyboard, too, but it's hardly ever used for anything.
The relative layouts look something like this:
PC: Ctrl Windows Alt
Mac: Ctrl Opt/Alt
The problem is that you're most likely using a PC keyboard on your Mac. In that specific case, the Opt/Alt and keys are reversed. You can change this in System Preferences, under Keyboard. Truly a huge pain in the rear for switchers. That layout looks like this, instead:
PC keyboard on Mac: Ctrl Opt/Alt
