How do you underscore on a Sony vaio?

To type an underscore (_) on a Sony Vaio laptop, hold down the "Shift" key and then press the hyphen (-) key, which is typically located next to the "0" key on the top row of the keyboard. This combination will create an underscore character. If you're using a different keyboard layout, the key positions may vary slightly, but the Shift + hyphen command generally remains the same.
