Left and Right Arrow Keys Do Not Work
I own a Macbook Air (13-inch, Mid 2011). This morning I updated the software on my laptop to OS X Yosemite and now my left and right arrow keys do not work. The keys worked perfectly fine before I updated the software. Is anyone else experiencing the same thing? How do I fix this?
