Keyboard Shortcuts
Overview
Keyboard shortcuts are combinations of keys that perform specific commands quickly, eliminating the need to navigate through menus. For the HSSC CET, this topic carries significant weightage in the Computer Knowledge section because it tests practical, everyday computer skills that every government employee must possess.
Questions typically ask you to identify the shortcut for a given action (e.g., "Which key combination is used to paste text?") or the action performed by a given shortcut (e.g., "What does Ctrl+Z do?"). Mastering 40–50 common shortcuts across Windows OS and MS Office applications (Word, Excel, PowerPoint) is sufficient for this exam. The good news: shortcuts follow logical patterns, making them easier to memorise once you understand the underlying system.
Focus on universal shortcuts (Ctrl+C, Ctrl+V) that work across applications, then learn application-specific shortcuts for Word, Excel, and PowerPoint. The exam rarely tests obscure shortcuts—stick to the most frequently used ones.
Key Concepts
- Modifier keys are the foundation of shortcuts: Ctrl (Control), Alt (Alternate), Shift, and the Windows key. Most shortcuts combine one modifier with a letter or function key.
- Ctrl-based shortcuts are the most common and typically relate to editing and file operations (Copy, Paste, Save, Undo).
- Alt-based shortcuts usually access menus and dialog boxes. Alt+F4 closes programs; Alt+Tab switches between open windows.
- Function keys (F1–F12) perform standalone actions: F1 for Help, F2 for Rename, F5 for Refresh, F11 for Full Screen.
- Shift key often modifies another shortcut to do the opposite action: Ctrl+Z (Undo) vs Ctrl+Y or Ctrl+Shift+Z (Redo).
- Windows key shortcuts control the operating system: Win+D shows desktop, Win+E opens File Explorer, Win+L locks the computer.
- Shortcuts are transferable—Ctrl+C for Copy works in Windows, Word, Excel, PowerPoint, and most other applications.

Worked Examples
Example 1: You are typing a report and accidentally delete an entire paragraph. Which shortcut will restore it?
Solution: Press Ctrl+Z to Undo. This reverses the last action. If you need to undo multiple actions, press Ctrl+Z repeatedly. The correct answer is Ctrl+Z.
Example 2: In MS Excel, you need to enter today's date in a cell quickly. What should you press?
Solution: Position cursor in the desired cell and press Ctrl+; (semicolon). This inserts the current system date. Note: For current time, use Ctrl+Shift+; — the Shift key adds the time component.
Example 3: You have 10 applications open and want to switch to your Word document without using the mouse. What do you press?
Solution: Press Alt+Tab and hold Alt. A window preview appears showing all open applications. While holding Alt, press Tab repeatedly until Word is highlighted, then release both keys. Word becomes the active window. Answer: Alt+Tab.
Example 4: In MS Word, a paragraph needs to be centre-aligned for a heading. Which shortcut achieves this?
Solution: Select the text (or place cursor anywhere in the paragraph) and press Ctrl+E. Memory trick: E = cEntre. Similarly, Ctrl+L = Left, Ctrl+R = Right, Ctrl+J = Justify.
Common Mistakes
- Confusing Ctrl+C (Copy) with Ctrl+X (Cut): Copy leaves the original intact; Cut removes it. If asked about moving text, the answer involves Cut (Ctrl+X), not Copy.
- Mixing up Ctrl+Z (Undo) and Ctrl+Y (Redo): Undo reverses your last action; Redo reverses the Undo. If you press Undo by mistake, Redo brings back what you undid.
- Forgetting that F2 has different meanings: In Windows Explorer, F2 renames a file. In Excel, F2 edits the active cell. Context matters—read the question carefully.
- Assuming Ctrl+S creates a new file: Ctrl+S saves the current file; Ctrl+N creates a new file. These are frequently swapped in exam options.
- Confusing Alt+F4 (close program) with Ctrl+W (close window/tab): Alt+F4 closes the entire application; Ctrl+W closes only the current tab or window within an application. In a browser with multiple tabs, Ctrl+W closes one tab while Alt+F4 closes the browser completely.
Quick Reference
- C-X-V-Z: Copy, Cut, Paste, Undo — the four most tested shortcuts.
- Win+L locks, Win+D shows desktop, Win+E opens Explorer.
- F1 = Help, F2 = Rename, F5 = Refresh — memorise these three function keys.
- Ctrl+B/I/U = Bold/Italic/Underline — works in Word, Excel, PowerPoint.
- Excel dates: Ctrl+; for date, add Shift for time (Ctrl+Shift+;).
- Alt+Tab switches apps, Alt+F4 closes them — Tab navigates, F4 terminates.
