Which function key is used for opening help ?
- A.F1
- B.F2
- C.F4
- D.F3
Correct answer
Explanation
The correct answer is A, F1. F1 is the function key that opens Help in Windows and in almost every Microsoft Office program, which is why it is the first key on the row. The twelve function keys F1 to F12 sit along the top of the keyboard and each carries a standard job. F2 renames a selected file in Windows Explorer and moves the cursor into the edit line in Excel. F3 opens the search or find box in Explorer and in most browsers. F4 repeats the last action in Word and switches a cell reference between absolute and relative in Excel, while Alt + F4 closes the active window. F5 refreshes a web page and starts a slide show in PowerPoint. F7 runs the spelling and grammar check in Word. Options B, C and D are wrong because F2, F4 and F3 do the jobs described above and none of them opens Help. Exam tip: F1 Help, F2 rename, F3 search, F5 refresh, F7 spell check, F12 Save As.
