A key that moves the cursor or insertion point backward one character space. In addition to moving the cursor backward, the Backspace key usually deletes the character to the left of the cursor or insertion point. It is particularly useful, therefore, for correcting typos. Note that PCs also have a Delete key, which deletes the character under the cursor (or to the right of the insertion point). To move the cursor or insertion point backward without deleting characters, use the arrow keys.
