Ctrl + F5 in Excel is used to restore the window size of the selected workbook window to its default size. This is different from F5 which opens the Go To dialog, or Ctrl + F4 which closes the current workbook window. Ctrl + S saves the file and Ctrl + T has different functions depending on the Excel version. The F5 key with Ctrl modifier specifically deals with window restoration.

Ctrl + D is the keyboard shortcut used to Fill Down in Excel, which copies the content and formatting from the cell above to the selected cell or range. This is a commonly used shortcut for quickly filling data vertically. The other options like Ctrl + 3 and Ctrl + 5 are not standard Excel shortcuts for filling, and Ctrl + F10 is used for maximizing or restoring the workbook window.

Ctrl + 7 is the keyboard shortcut used to show or hide the Standard toolbar in Excel. This shortcut toggles the visibility of the toolbar, allowing users to customize their workspace. However, it's worth noting that in modern Excel versions with the ribbon interface, this shortcut may have limited relevance as the ribbon has replaced traditional toolbars. The other options (Ctrl + F4, Ctrl + 3, Ctrl + 4) are not used for toolbar visibility.

Shift + F9 is the keyboard shortcut used to calculate the active worksheet in Excel. This shortcut performs calculation only on the current sheet, unlike F9 which calculates all open workbooks. This is useful when working with large workbooks and you want to recalculate only the active sheet. The other options like Ctrl + 3, Shift + F7, and Alt + F7 are not standard calculation shortcuts in Excel.

Ctrl + Page Up is the keyboard shortcut used to move to the previous sheet in an Excel workbook. This shortcut allows quick navigation between worksheets without using the mouse. The complementary shortcut Ctrl + Page Down moves to the next sheet. The other options like Shift + K, Alt + P, and Alt + Q are not standard shortcuts for sheet navigation in Excel.

Ctrl + F6 is the keyboard shortcut used to move to the next workbook window when multiple Excel workbooks are open. This shortcut cycles through open workbooks, allowing users to switch between them efficiently. The complementary shortcut Ctrl + Shift + F6 moves to the previous workbook. The other options like Shift + R, Ctrl + Shift + Q, and Alt + Y are not standard shortcuts for workbook navigation.

Ctrl + R is the standard keyboard shortcut in Microsoft Excel and other spreadsheet applications to fill right. This copies the contents or formula from the cell(s) to the left into the current cell(s) to the right. It's the horizontal equivalent of Ctrl + D which fills down.

Ctrl + K is the universal keyboard shortcut for inserting hyperlinks across Microsoft Office applications (Word, Excel, PowerPoint, Outlook) and many other software programs. This shortcut opens the Insert Hyperlink dialog box, allowing you to link to web pages, files, or other locations within the document.

Ctrl + Z is the standard keyboard shortcut for undoing the last action in most Windows and Linux applications. It's a universal command that reverses the most recent action. Ctrl + S saves, Ctrl + F4 often closes a document or tab, and Ctrl + T usually opens a new tab.

In Microsoft Excel, Ctrl + Shift + : (colon) inserts the current time in the selected cell. This is a useful shortcut for quickly adding timestamps. The semicolon version (Ctrl + Shift + ;) inserts the date instead.

In Microsoft Excel, Ctrl + ; (semicolon) inserts the current date in the selected cell. This is a standard Excel shortcut that's useful for quickly adding today's date to a spreadsheet. The time shortcut uses Ctrl + Shift + : instead.

Ctrl + Y is the standard keyboard shortcut for 'redo' or repeating the last action in most applications. It's the opposite of Ctrl + Z (undo) and can repeat actions or redo undone steps. This shortcut works across most Windows software.

Shift + Insert is a traditional keyboard shortcut for paste, especially in Windows and command-line environments. It's an alternative to the more common Ctrl + V. Both work in most Windows applications, making it a useful backup paste command.

Ctrl + W is the universal keyboard shortcut to close the current document or tab in spreadsheet software like Excel and Google Sheets. This shortcut works consistently across most spreadsheet applications.
