CTRL + SHIFT + # applies Date format in Excel. The hash symbol is used for date formatting, though not as intuitively named as other shortcuts.

In Microsoft Excel, the keyboard shortcut CTRL + SHIFT + @ applies the Time format to selected cells. This is a standard Excel formatting shortcut that converts cell contents to a time display format (e.g., 1:30 PM). The other combinations shown are for different formats or functions.

In Excel, CTRL + SHIFT + ! applies the Number format with two decimal places and thousand separators. This is a standard formatting shortcut that makes numbers more readable by adding commas and fixed decimal places. The other options are for different Excel functions.

CTRL + F6 is the Excel keyboard shortcut that cycles between open workbook windows. This allows users to switch between different Excel files they have open without using the mouse. The F10 and F9 keys have different functions in Excel, and SHIFT + DOWN ARROW is for cell selection.

SHIFT + SPACEBAR is the Excel keyboard shortcut that selects the entire row where the active cell is located. This is a quick way to highlight all cells in a particular row. The other options are for different selection or navigation functions.

CTRL + SHIFT + ^ applies the Exponential (Scientific) number format in Excel. This converts numbers to scientific notation (e.g., 1.23E+10). The caret symbol (^) represents exponentiation, which hints at this function.

CTRL + SPACEBAR is the Excel shortcut that selects the entire column where the active cell is located. This is different from SHIFT + SPACEBAR (which selects a row). The other options are for different functions.

The shortcut ALT + = (holding Alt and pressing the equals key) inserts a SUM AutoSum formula in Excel. This automatically selects the range of cells above or to the left of the current cell and inserts the SUM function, making it quick to add up columns or rows of numbers.

The shortcut CTRL + SHIFT + " (double quote) copies the value (not the formula) from the cell directly above into the current cell. This is different from copying the formula - it copies only the resulting value, which is useful when you want to preserve a calculated result.

The shortcut CTRL + ' (apostrophe/single quote) copies the formula from the cell directly above into the current cell. This is different from copying just the value - it copies the entire formula so that the current cell will calculate using the same logic, adjusting relative references if needed.
