The formula bar is a section in the spreadsheet application where you can view and edit formulas or input data.

Clicking this button opens the formula for editing. The cancel button, often represented by an "X" or a cancel icon, allows you to discard any changes made to the formula and revert to the original formula or data. The enter button, often represented by a checkmark or an enter icon, allows you to confirm and apply the changes made to the formula in the formula bar. Clicking this button finalizes the edited formula or data. So, when the formula bar is active, all of the mentioned options (the edit formula button, the cancel button, and the enter button) are visible.
