SUM function can be quickly entered in a cell by pressing ........ in Excel.

The AutoSum feature in Excel is one of the fastest ways to calculate the total of a column or row of numbers. Instead of typing out =SUM(A1:A10) manually, you can simply use the keyboard shortcut:

1. Select an empty cell immediately below a column of numbers or to the right of a row of numbers.

2. Press Alt and = simultaneously.

3. Excel will automatically write the SUM formula and highlight the adjacent data range.

4. Press Enter to confirm and display the final total.
