I pressed *something* and now the screen on my main display is magnified. I have a MacBook Pro and also use an additional screen for dual display. I am pretty sure I was just pressing the F7 key to adjust the display when the main screen (the one attached to my laptop) magnified everything on it. I searched the forums and tried the fix of going to Universal Access to turn off Zoom and that wasn't the problem. I don't have a mouse so I can't do anything with the scroll wheel on the mouse. Restarting also did not help, and neither did disconnecting and reconnecting the second screen. Any help is greatly appreciated!
