The solution to lower caSe "S" key is so intuitive, not.
http://www.macworld.com/forums/ubbthreads/showflat.php?Cat=0&Number=481403&an=0&page=0#481403Just figured out and fixed the problem. In system preferences > speech > spoken user interface > Other spoken items, i deselected the "Selected text when the key is pressed" box. Problem solved. I feel like an idiot now since I'm the one who caused the problem in the first place!
