How do I select a cell in Excel using the space bar?

To select a cell in Excel using the space bar, you first need to make sure that the 'Enable selection' option is turned on. To do this, go to 'File' > 'Options' > 'Advanced' and make sure that the 'Enable selection' option is checked. Once you have done this, you can simply move your cursor to the cell that you want to select and press the space bar. This will select the cell, and you can then use the arrow keys to move to other cells while keeping the original cell selected.
