Hello evryone, I just bought an iMac and, I don`t know how but my keyboard lost it`s configuration. All my function buttons are messed up. I went to system prefs to change short cuts but didn`t find the correct config to fit play, foward, rewind and volume controls. I tried to just "restore defaults" but it's still messed up. sorry about this post I know it sounds like a pretty dumb question but I couldn`t figure it out myself. Vanessa.
