uControl has the ability to swap keys. i have the return key mapped as a function key. and with this i can hold it down with my right pinky and scroll the trackpad for some one handed websurfing, since i can not _quite_ reach the left return and scroll comfortably.
in 10.2.4 it worked fine. in 10.2.5 it seems to be extremely laggy. i have to run my finger across the track pad fast to scroll it.
anyone feel like trying it out for me and tell me their findings?
