i moved my iMac when it was on to avoid getting water on it - after that the text to speech is now enabled and I cannot seem to turn it off. I have tried to change or reset it on the system preferences, speech ,text to speech but can't seem to change anything. There were no key functions assigned so I assigned Control z and tried turning on or off but to no effect. Also the key board functions are changed. For example the volume (f12) activates the dashboard. When I hold the fn key down the functions are correct. I tried to reset the functions to default in system preferences - keyboard but nothing changes. Nothing got wet - I think I must of hit some combination of keys to mess this up. Any help would be greatly appreciated.
