After installing Mavericks, my up arrow copies in excel

After installing Mavericks, my up arrow copies in excel. While copying the cell, it will also speak the number or word int he cell. I went to system preferences/dictation & speech and changed Speak selected text when the key is pressed to F19. I even turned off speak selected text when the key is pressed and it still copies cells and reads the text or number it copied. If I highlight a word in MS Word, for example, and hit the up arrow, it will read what I have hightlighed. When I hit F19 (what I changed that feature to), it also reads what I have highlighted. I went into Excel & Word and there is no shortcut for just the up arrow. Any idea how to turn my up key back into an up key?
