Basic Computer: General Shortcuts & Function Keys MCQ — 15 Practice Questions with Answers

Explanation

Assertion (A) is correct: in Windows, Alt+Tab brings up the task switcher and lets the user move between open applications or windows. Reason (R) is also a true statement about the Tab key by itself; it is used in forms to move to the next field and in spreadsheets to move to the next cell. However, that ordinary Tab function does not explain why Alt+Tab switches windows. Since both statements are true but the reason is not the explanation, option B is correct.

Explanation

The question specifies that a file is already selected in File Explorer. In Windows, pressing F2 when a file or folder is selected activates the rename field, allowing the user to type a new name directly. This is faster than opening the right-click context menu. The nearby function keys have different standard uses: F1 opens Help, F5 refreshes, and F11 often toggles full-screen mode. Hence, for renaming a selected file or folder, F2 is the correct shortcut.

Explanation

The clue is the word Help. Across many Windows programmes and standard computer textbooks, F1 is taught as the function key for opening the Help window or help section of the active programme. Other function keys have different common uses: F2 is linked with renaming a selected item, F5 with Refresh or slideshow actions, and F11 with full-screen view in many programmes. Therefore, when the question asks for the key used to open Help, the defensible answer is F1.

Explanation

Ctrl+S is the standard shortcut for saving the current file in common applications such as Word, Excel, Notepad and many browsers. The stem deliberately contrasts saving with Print and New File commands. Ctrl+P opens printing, Ctrl+N creates a new file or window, and Ctrl+O opens an existing file. Since the required action is to save the file already being edited, Ctrl+S is the correct shortcut.

Explanation

The cue in the question is "save the current file or document". In standard Windows software, including MS Word, Excel, Notepad and many browsers, Ctrl+S is the common Save shortcut. It writes the current changes to the existing file, or opens the save dialog if the file has not yet been named. Ctrl+P, Ctrl+N and Ctrl+O are neighbouring common shortcuts, but they mean Print, New and Open respectively. Therefore, the defensible answer is Ctrl+S.
