Microsoft Word: My Experience and Shortcomings

My previous experience with Microsoft Word encompasses a semester of Computer Science in high school and typing a couple papers using the program. I have never had Microsoft Office on my personal computer before this year. I have always had Microsoft Works, which may explain my lack of Microsoft Word skills. I would like to brush-up on basic text-editing skills such as using the "Replace" tool on the home ribbon, making text superscript or subscript, and using tab and tab stops.
