Which key do you use to delete the last character typed?

The Backspace key is specifically designed to delete the character immediately to the left of the cursor. This function allows the user to quickly remove mistakes while typing. When pressed, the Backspace key eliminates the last character entered, making it essential for correcting errors or refining text without having to retype everything from that point onward.

In contrast, the Enter key serves primarily to submit a command or create a new line in text, the Space bar is used to insert spaces between words, and the Tab key is utilized for navigating between fields or creating indents. Therefore, the Backspace key is the appropriate choice for deleting the last character typed in any text context.
