Who had the [ALT]+[TAB] function first, MAC or PC? I used to use it a lot when I had PCs but with MAC, I find myself using the Expose function instead. Its a lot easier. I started wondering why MAC even had the [ALT]+[TAB] function as a feature. Was it part of the old MAC OS and Windows copied it? Did MAC copy it from Windows? I remember using it with Windows even with Windows 95 (I think).
