somehow this only happened recently (ie, somehow wasn't happening till today)
but on ST3 on my mac, I can't use the option+ left /right arrow keys to jump between words. I'm quite certain i was doing that earlier this week
Somehow uninstalling the current head version of the st3 sublime haskell plugin borked option keys. I had to wipe my st3 install and setup everything again to get the os x standard option + left/right arrow behavior again.
