Hello. I just got my first Mac about a month ago. I am a college student in the Bachelor's of Science in Information Technology - so I feel really silly asking this question. I am working in Aptana Studio trying to correct my web page for an assignment. One of the words in the source code is bolded and when I hold my mouse over the word, a message displays telling me to press "F1" for help. However, every single time I try, it decreases the brightness instead of providing help. What is the deal? Is there some key combination I have to try to get the button to provide help? I have tried fn+F1, Control+F1, Option+F1, and Command+F1 and NOTHING works.
