Sorry about that. I was clearly so proud of myself for getting my keyboard to do the two dot thing on top of the Ö that I forgot the most basic link of all. Updated now.
If you're new to OSX I highly recommend playing about seeing which characters are possible. Hold Option and try each key, then Option+Shift and each key. Comes in handy for typing things like ©2013, 20˚, 2π and LÖVE
