In MS Word and many other text editors, the shortcut Ctrl + End moves the cursor to the last line of the document.

In MS PowerPoint, pressing Ctrl + Home takes you to the first slide of your presentation, regardless of your current location in the slide deck.

An electronic spreadsheet, such as Microsoft Excel, consists of:

• Rows: Horizontal lines of cells, labeled with numbers.
• Columns: Vertical lines of cells, labeled with letters.
• Cells: The intersections of rows and columns where data can be entered.

Therefore, an electronic spreadsheet is made up of all these elements: rows, columns, and cells. Hence, the correct answer is All of the above.
