CTRL+W is the universal keyboard shortcut to close the current window or tab in Internet Explorer and most browsers. This shortcut works across many applications for closing documents or tabs. The other options are different shortcuts: CTRL+C copies selected text, CTRL+D bookmarks the current page, CTRL+L focuses the address bar, and CTRL+M varies by application.

ALT+SPACEBAR is the standard Windows shortcut that opens the system menu (shortcut menu) for the active window. This menu contains options like Restore, Move, Size, Minimize, Maximize, and Close. This shortcut has been a consistent feature in Windows for decades. The other options are not valid Windows shortcuts.

CTRL+SHIFT+ESC is the direct keyboard shortcut to open Task Manager in Windows. While many users know CTRL+ALT+DELETE (which also provides access to Task Manager), CTRL+SHIFT+ESC takes you directly to Task Manager without an intermediate screen. This is the fastest way to launch Task Manager. The other options are not valid shortcuts for this purpose.

Windows Logo+SHIFT+M restores all minimized windows to their previous state. This is the opposite of Windows Logo+M (which minimizes all windows) or Windows Logo+D (which shows the desktop). Once you have minimized windows, this shortcut brings them all back at once. The other options are not standard Windows shortcuts for this purpose.

In Excel, Ctrl+F5 serves to reset the active workbook window to its previous or default size. This shortcut differs from F5 (Go To dialog) and Ctrl+S (Save), which are commonly confused alternatives.

Ctrl+D fills cells downward by copying the content from the cell directly above. This is a fundamental Excel shortcut for quickly replicating data across multiple rows without manual entry.

Shift+F11 inserts a new blank worksheet into the current workbook. Ctrl+F4 closes the current sheet, while numbered combinations with Ctrl are not standard worksheet insertion methods.

Shift+F9 recalculates all formulas in the active worksheet only. This differs from F9 which calculates the entire workbook, making it useful when working with large files to save time.

Ctrl+Page Up navigates to the previous worksheet tab in the workbook. This provides quick leftward movement through sheets without using the mouse.

Ctrl+F6 switches to the next open workbook window. This is the standard shortcut for cycling between multiple Excel files when more than one is open.

Ctrl+Backspace scrolls the sheet to make the active cell visible in the window. This is useful when you've scrolled away and need to quickly return to your working position.

Ctrl+R fills the contents to the right, copying from the cell to the left. This complements Ctrl+D (fill down) as the horizontal equivalent for data replication.

Ctrl+K opens the Insert Hyperlink dialog box in Excel. This allows you to create links to web pages, files, or other locations within your spreadsheet.

Ctrl+F5 resets the selected workbook window to its standard size. This differs from F5 (Go To dialog) and Ctrl+S (Save), which are frequently mistaken alternatives.

Ctrl+D fills cells downward by copying from the cell directly above. This provides efficient vertical data replication across multiple rows.
