The top five sections in the Excel Options window let you tweak a wide variety of different details. Some of these details are truly handy, like the options for opening and saving files. Others are seldom-used holdovers from the past, like the option that lets Excel act like Lotus an ancient piece of spreadsheet software when you hit the "/" key.
Beneath the top five sections are four more specialized sections:
