In MS-Excel 2010, click the cell that contains the data that you want to edit and then press ______ key. It starts Edit mode and positions the cursor at the end of the cell contents.

Correct option is A

The correct answer is (a) F2
Explaination:
· Pressing the F2 key is the standard keyboard shortcut in MS-Excel to enter Edit mode for the selected cell.
· Once pressed, the cursor is automatically placed at the end of the existing text or formula within that cell.
· This allows users to make changes directly inside the cell rather than having to click the formula bar at the top.
Information Booster:
· In addition to the F2 key, you can also enter Edit mode by double-clicking the cell or by clicking anywhere inside the Formula Bar.
· To cancel edits and exit Edit mode without saving changes, you can press the Esc (Escape) key.
Additional Knowledge:
· F3: In Excel, this key is used to display the "Paste Name" dialog box (if you have defined names in the workbook).
· F4: This key is used to repeat the last action or, when editing a formula, to cycle through absolute and relative cell references (e.g., changing A1 to $A$1).
· F1: This is the universal shortcut to open the Excel Help window or task pane.
