Hello, Just bought a MacBook Pro 13" Core-i7 non-retina model. I haven't used Mac OS X before. So, I am still learning on how to use it. The problem is fn + function key combination doesn't seem to work. Suppose when I have a tab open and highlighted in Google Chrome, and if I press fn + F5 it doesn't refreshes the page. Even pressing fn + F1 doesn't brings up the help window. Am I missing something? Is there any specific setting which I need to do? Tried googling it but got no useful solution. Posting here after a long long time. Thanks and regards.
