Spacebar
Alternatively known as space and the space key, the spacebar or space bar is a long horizontal key on the lower edge of a keyboard. It's always the largest and longest key on the keyboard. When the spacebar key is pressed, it creates an empty space known as a space character or whitespace that helps separate words and other characters in a sentence. For example, if there were no spaces in this paragraph, all of the text would be together and difficult to read.
When the keyboard is positioned in front of you, the spacebar should be in the center of your body.
