Shift + F7 is the correct keyboard shortcut to open the Thesaurus in MS Word. This feature helps find synonyms and antonyms for selected words. The other options (F9, F4, F6) perform different functions or are not standard thesaurus shortcuts.

Ctrl + F9 minimizes the current workbook window in Excel. This is the correct shortcut for window minimization. Ctrl+F4 closes the workbook, Ctrl+F2 opens the print preview, and Ctrl+F5 restores a minimized window.

Ctrl + F6 switches between open Excel workbooks/windows. This is the correct navigation shortcut. Ctrl+F4 closes the current workbook, Ctrl+F2 opens print preview, and Ctrl+F5 restores a maximized window to normal size.

Ctrl + ; inserts the current date in Excel. This is the correct shortcut. The semicolon key is used for date entry. Ctrl+: (colon) would insert the current time. The other options are not standard date entry shortcuts.

F11 creates a chart in Excel using the selected data. This is the correct shortcut and will instantly generate a default chart on a new sheet. F7 is spelling check, F5 is Go To, and F9 recalculates formulas.

The '#' symbol is called an octothorpe (or octothorp). The name comes from 'octo' for its eight points and 'thorpe' (possibly from Thor or a surname). It's also commonly called the pound sign or hash key.

Windows + E is indeed the keyboard shortcut to open 'My Computer' (now called 'This PC' or 'File Explorer' in newer Windows versions). This shortcut directly opens File Explorer and displays the computer's drives and system folders, making it a useful quick access command.

Windows + D is the correct keyboard shortcut to show the desktop by minimizing all open windows. Pressing it again restores the minimized windows, making it a useful command for quickly clearing the screen or accessing desktop icons and files.
