Alt+↓ is absolutely one of my frequently used shortcuts when using Excel.
What it does? “Open sesame” under four common circumstances. 🙂
When you are at the bottom of a column
Alt+↓ displays the list of items on the column.
So good for inputting value without retyping –> Minimize chance of typo
When you are on the top row of a table with auto filter on
Alt+↓ opens the filter box. (Same effect as clicking the drop down button)
When you are on a cell with Data Validation (validated by list)
Alt+↓ opens the available options for the cell. (Same effect as clicking the drop down button)
When you are on a row/column label / report filter on Pivot Table
Alt+↓ opens the filter box for the field. (Same effect as clicking the drop down button)
To make it short, Alt+↓ opens available option, if any, of the active cell.
