Microsoft Excel

I've been teaching a software class here at my new job once a week for the month of August and will for the month of September. August is on the essentials of Excel, from entering data, formatting cells to sorting and filtering data and creating charts. It's enjoyable to teach this application to others here in the company and I still learn a few new things along the way as well. For example, I always knew that if you select a range of cells (select and drag your mouse over a number of cells) or select dis-joined cells (hold the control key and click on different cells). I knew that in the status bar Microsoft Excel would then total (sum) these values for you. What I didn't know is if you right-click on the sum that is displayed, you can select to average, count, get the minimum or maximum of the values selected instead of just the sum. Pretty cool.
