A "blinking vertical bar" typically refers to a cursor or insertion point that appears as a vertical line on a computer screen, indicating where text will be inserted when typing. This cursor blinks to draw attention and signal that the system is ready for user input. It is commonly seen in text editors, word processors, and command-line interfaces.
