Which key is used to delete a character to the left of the insertion point?

The Backspace key is specifically designed to delete a character located immediately to the left of the insertion point. When this key is pressed, the cursor moves back one position and removes the character that was previously there. This functionality is essential for correcting mistakes as it allows users to quickly erase text without needing to navigate away from their current position.

Other keys serve different purposes: the Enter key is primarily used for confirming commands or creating a new line; the Delete key removes characters to the right of the insertion point, and the Shift key modifies the input of other keys, allowing for capital letters or alternative characters when used in combination. Understanding these key functions is fundamental for efficient keyboarding and text editing.
