Alt+F4 is the standard Windows shortcut to close the active application. For closing just the current database window in MS Access (without exiting the application), Ctrl+W or Ctrl+F4 might also work, but Alt+F4 is the most direct and universally recognized close command.

Ctrl+W is the standard keyboard shortcut to close the current Datasheet view in MS Access. This works similarly to closing documents in other Windows applications. Ctrl+C is for copying, Ctrl+O is for opening, and Alt+F4 closes the entire application.

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.
