I have seen many posts that are having trouble getting FuzzyFinder to work in MacVim. In certain configurations you will see multiple errors “E806: using Float as a String”. This is because some locales make MacVim treat floating point numbers differently. Here is how I did to make it work on my system (OS X 10.6.4 and MacVim 7.3). As an added bonus we will map it to the Apple-T key and default it to subdirectory search.
