Boring story...(you can skip this part)
I've always favored using the best tool for the job at hand. This is something I learned along time ago when working with my grandfather in his workshop. If you have a nail then the tool to use is a hammer. Probably not just any hammer either, there are actually hammers designed to drive nails and ones that aren't. Of the ones designed to drive nails there are different sizes and different manufacturers. Sometimes the manufacturer makes a difference and sometimes it doesn't. I've never forgotten those years and I always have looked to apply those same principals in choosing technologies to work on various software projects during my 28 years developing software commercially. That's what left me trying to use the keyboard I have grown quite use to using with the new Mac Mini that I just recently started using. In this instance writing code is the nail and my hammer of choice is the...
Microsoft Natural Ergonomic Keyboard 4000 v1.0It is perfect for me. Unfortunately, even with the Microsoft supplied Mac OS X Intellipoint device drivers the keyboard was frustrating to use on the Mac Mini. The most frustrating point was the number pad NumLock key. It simple didn't function as a NumLock. The keypad on this keyboard when attached to the Mac OS X 10.8 (Mountain Lion) operating system was simply always in number mode. I use the number pad to navigate around my code and it simply would no longer work. I was frustrating myself trying to use the keyboard. I would edit code and constantly being inserting 2's, 4's, 6's and 8's. What a mess. Countless searches trying to find a solution turned up many people who shared my problem but NO solutions. I started to contemplate, was it time for a new hammer? I think not!
As luck would have it I found an answer!
We despite the title it worked for my Mac Mini. In no time at all this genius little utility fixed the issue for me by making the NumLock key work. I was so happy I donated to his cause so he could have a couple beers on me.
If you decide to use the utility to solve this particular problem I can save you some time looking through the hundreds of settings available with this utility. Once you have it installed. Go to System Preferences -> Other -> KeyRemap4MacBook then choose the section labeled "For PC Users" and you'll see a few different options. The one you want is:
"Use clear key to toggle "Keypad as Arrow (PC Style Home/End/PgUp/PgDn)"
In addition to that setting there are a few others under this same section that will likely help you out if you're like me and spend a majority of your day using a Windows OS.
As always I hope this helps someone with the same issue I was having.
