So I was playing with various combinations of apple/option/shift and the f-keys to see what kinds of things were mapped to them, and it turns out I've done two annoying things. The first is some sort of accessibility thing where when I type things or click on things, some strange voice tells me everything I'm doing, and the poor guy is trying to do it in real time, but I just type faster than he talks. The second is that I used to be able to use the function keys (volume, Expose, brightness, etc) shortcuts without using the Fn key, but now I either use that key or it does something wrong (F12, for example pulls up Dashboard without Fn, and with it, it increases volume, just like it should. So what do I do to fix it?! Thanks.
