Help, I'm a PC person using a Mac for the first time in years. I was trying to copy some text and hit control C and the next thing I know the images on the monitor are enlarged. I'd like to get back to the normal settings. Anyone know what I did and how to get back to the regular settings (it also may have been that it happened with control v, I do the two so quickly, it may have been on the second of the two that things changed).
