answer:You can freeze a first column or row so you can always see it. That way if say the top row has headers like Quantity of Beds, Quantity of Dressers, Quantity of Chairs, etc, you don’t have to remember which column was what or keep scrolling back and forth to make sure you are looking at the right column for the information. It’s very helpful with long documents of data. If you double click in a cell where you already wrote something you can edit the cell. You can have a cell automatically grow in height with how much information you type by using the “wrap” function. There is a way for information from one cell on a page in a workbook to automatically copy into a cell on another page in the same workbook. I use this when information I need to send someone is calculated on one page, but the receiver should not see all the information, just final numbers. I just save and send the single page with limited information as a PDF, and I didn’t have to do much if anything to create that document with limited information. If you click in the top left corner it highlights the entire document so you can make formatting changes for the entire document in one swoop.
