Settings in Excel 2016
You can greatly reduce data-entry problems in your workbooks by making Excel check entries before entering them in specific cells. To do so, you need to define restrictions and data-validation rules for those cells.
By default, number of Undo levels in Excel 2016 is 100. You can increase or decrease this number, if it's necessary.
When you first start most of the Office 2016 applications, you'll see a new feature called the Start screen.
If you prefer to avoid the empty workbook to be created when Excel starts up, you can do so by editing the command line that is used to start Excel.
Excel 2016 automatically creates one worksheet in each new workbook, but you can force it to create as many worksheets as you need.
By default, Excel shows document tooltips (or screentips) when you hover on a button, but this option can be turned off.
When you need as much space as possible on screen to view a document, you can collapse (or minimize) the Ribbon and then restore it very simple.
