Tip #33. If you open a pop-up option box and realize you didn’t want to do anything, close it by clicking on Cancel. That’s a lot safer than clicking on OK. You might have changed something without noticing it and clicking on OK will make changes to your document. This tip is good at any time you want to close without making changes in any application on your computer.
