Which of the following shortcuts allows for canceling an operation?

• A. CTRL+W
• B. ESC
• C. CTRL+K
• D. CTRL+D

Answer: (B)

The ESC key is commonly used in many computer applications and environments to cancel an operation or exit from a current task. It serves as an immediate way to stop an ongoing action, whether it's closing a dialog box, stopping a process, or exiting a full-screen mode. This functionality makes it a universal shortcut that users can rely on across various software programs. In contrast, other options serve different purposes. For instance, CTRL+W typically closes the current window or tab in many browsers and applications, while CTRL+K might insert a hyperlink in word processors. CTRL+D is often used for actions like duplicating an item or bookmarking a page, depending on the context of the application being used. Understanding these distinctions helps users navigate their tools more effectively and utilize the correct shortcuts for their intended tasks.
