Shortcut Keys (Computer Basics)

Ctrl+I is the universal keyboard shortcut for applying italic formatting to selected text in most applications including Microsoft Word, Excel, and PowerPoint. The other options either do nothing or perform different functions - Alt+I has no default action, Ctrl+C is for copying, and Alt+C has no standard formatting purpose.

Shift+Delete is the Windows keyboard shortcut that permanently deletes selected files or items without sending them to the Recycle Bin. Regular Delete moves items to the Recycle Bin where they can be recovered, while Ctrl+Delete and Alt+Delete have no standard file deletion function in Windows Explorer.

Ctrl+A is the universal 'Select All' shortcut across Windows applications and web browsers. It instantly selects the entire document or all text in the current text field. Alt+A and Shift+A have no standard selection function, while Shift+Right Arrow only selects text character by character, not everything at once.

Ctrl+D opens the Font dialog box in Microsoft Word, giving access to all font formatting options. This shortcut provides quick access to font family, size, style, color, and effects. The other options - Ctrl+B (bold), Ctrl+F (find), and Ctrl+J (justify) - perform different formatting functions and do not open the Font dialog.

Ctrl+K is the standard shortcut for inserting hyperlinks across Microsoft Office applications and many other programs. This shortcut opens the Insert Hyperlink dialog box. The other options are incorrect: Ctrl+H is for find/replace, Ctrl+L for left align, and Ctrl+U for underline - none of these insert links.

Ctrl+Shift+Plus (Ctrl+Shift+=) applies superscript formatting in Microsoft Word, raising text above the baseline. The plus sign is typically the same key as the equals sign on standard keyboards. Ctrl+Shift+Minus is for subscript (lowering text), while Ctrl+Shift+S has no direct formatting relation to superscript.

Ctrl+Shift+A converts selected text to all capital letters (ALL CAPS) in Microsoft Word. This is a case conversion shortcut, not a formatting toggle like bold or italic. The other options are incorrect: Alt+Shift+A has no standard function, Ctrl+Shift+C copies formatting, and Alt+Shift+C has no default action.

Ctrl+Shift+C copies the formatting of selected text in Microsoft Word, allowing you to apply that same formatting to other text (like the Format Painter tool). After copying formatting with Ctrl+Shift+C, you paste it elsewhere with Ctrl+Shift+V. The other options perform different functions: Ctrl+Shift+F opens the Font dialog, Alt+Shift+C has no standard meaning, and Ctrl+Shift+P opens the Format Paragraph dialog.

Alt+Tab is the standard Windows shortcut for switching between open applications and windows. It displays a task switcher showing all open programs, allowing you to cycle through them. Ctrl+Tab switches between tabs within the same application (like browser tabs), while regular Tab and Shift+Tab only move between elements within the current window.

Ctrl+Y is the keyboard shortcut for 'Redo' - it repeats the last action or reverses an undo. This works in most applications including Microsoft Office. Note the typo in option D: 'Clt' should be 'Ctrl'. Ctrl+R is typically for refresh or right align, Ctrl+Q for quit or other functions, and the typo 'Clt+y' is invalid.

Ctrl+M indents the selected paragraph from the left in Microsoft Word, increasing the left margin spacing. This is the standard indent shortcut. The other options are incorrect: Alt+M has no default function, Ctrl+I is for italic formatting, and Ctrl+D opens the Font dialog - none of these indent paragraphs.

Ctrl+B is the universal keyboard shortcut for applying bold formatting to selected text across all major applications and word processors. This is one of the most fundamental formatting shortcuts. The other options are incorrect: Alt+B has no standard function, Shift+B does nothing in most programs, and Ctrl+O opens the Open File dialog.

Ctrl + T creates a hanging indent in Microsoft Word, which indents all lines except the first line of a paragraph. This is commonly used for bibliography entries and reference lists. The other options (Ctrl+H for replace, Ctrl+G for Go To, Alt+T for tools menu) perform different functions.

Alt + F4 is the universal Windows shortcut to close or quit the active application, including Microsoft Word. Ctrl + F4 closes only the current document window without quitting Word, while F2 and F2 variations are not quit commands. This is one of the most fundamental shortcuts in Windows.

Ctrl + E centers the selected text or the current paragraph in Microsoft Word. Ctrl + C copies, Ctrl + V pastes, and Ctrl + N creates a new document. Centering is a basic text formatting function and Ctrl + E is the standard shortcut across Microsoft Office applications.

Ctrl + W closes the current document in Microsoft Word without exiting the application. It prompts you to save changes if there are any unsaved modifications. Ctrl + T creates hanging indent, while the Shift and Alt variants listed are not standard document-closing shortcuts.

Alt + F10 maximizes the program window to full screen in Microsoft Word. This shortcut restores the window to its maximum size. F9 is used for updating fields, and while F10 alone activates the menu bar, Alt + F10 specifically maximizes the application window.

Ctrl + H opens the Replace dialog in Microsoft Word, which allows you to find and replace text, formatting, and special characters. Ctrl + R is right-align, while Alt + H and Shift + H are not standard replace shortcuts. The Replace dialog is a powerful tool for bulk editing.

Ctrl + F opens the Find dialog in Microsoft Word, used to locate specific text, formatting, or special items within your document. Ctrl + S saves, Ctrl + K inserts hyperlinks, and Alt + F opens the File menu. The Find command is essential for navigating long documents.

Ctrl + Delete deletes one word to the right of the cursor in Microsoft Word. Ctrl + Right arrow moves the cursor right by one word without deleting. Alt + Delete and Shift + Delete are not standard word-deletion shortcuts. This is useful for quickly editing text word by word.

Ctrl + Equal Sign applies subscript formatting in Microsoft Word, making text appear below the normal line (like in H2O). Subscript is commonly used for chemical formulas and mathematical expressions. Ctrl + Shift + Equal Sign would apply superscript, while Ctrl + * and Ctrl + ^ are not subscript shortcuts.

Ctrl + G opens the Go To dialog in Microsoft Word, which allows navigation to specific pages, bookmarks, footnotes, tables, comments, graphics, and other document locations. Ctrl + F opens Find, Ctrl + B makes text bold, and Ctrl + C copies. Go To is essential for navigating large documents quickly.

Ctrl + ] increases the font size by 1 point in Microsoft Word. This allows for precise font size adjustments. Ctrl + [ decreases the font size by 1 point. The bracket keys provide incremental size control, which is useful for fine-tuning text appearance.

Ctrl + Z undoes the last action in Microsoft Word, reverting changes step by step. This is the universal undo shortcut across Windows applications. Ctrl + X cuts, Ctrl + R redoes (or right-aligns depending on context), and Ctrl + U underlines text. Undo is one of the most frequently used commands.

Shift+F8 is the keyboard shortcut used to add to a selection in many applications, particularly in Microsoft Office programs like Word and Excel. This allows you to extend your current selection without using the mouse. Shift+F7, F4, and F5 have different functions (like spell check, repeat action, and refresh/Go To respectively).
