In Excel, the shortcut key for selecting one row to the last row is "Shift + Space + Ctrl + Arrow Down". Hold down the Shift key, then press the Spacebar to select the entire row, then hold down the Ctrl key to keep it selected, and press the Down Arrow keyboard button to extend the selection to the last row.
The brief steps are as follows:
- Move the cursor to the line where you want to start selecting.
- Hold down the Shift key.
- Press the spacebar (Shift + Space) simultaneously to select the entire row.
- Without releasing the Shift key and the Space bar, hold down the Ctrl key.
- Finally press the arrow key down keyboard button to extend the selection to the last row.
This way you can quickly select all rows from the current row to the last row. Note that this shortcut key combination may be slightly different in different versions of Excel. The specific shortcut key combination may vary depending on the version of Excel you are using and the settings of your operating system.
