What is the blinking line called when typing?

The blinking line that appears on a screen when typing is often referred to as the cursor. The cursor indicates the current position in a document or text input field where new characters will be inserted. It blinks or flashes to provide a visual cue to the user and helps them keep track of where they are typing.

The appearance of the cursor can vary depending on the program or application being used. In a word processor, the cursor may be a vertical line that moves to the right as you type. In a command line interface, the cursor may be a block that blinks as you type commands.

Some users may find the blinking cursor distracting, while others rely on it to guide their typing. Overall, the cursor serves as a useful tool for navigating and editing text on a computer screen.
