Correct option is C

S. Ans. (c)

Sol.
The primary function of the Tab key when navigating through options in a dialog box or menu is to move the focus to the next available option or control. This allows users to cycle through interactive elements such as buttons, text fields, checkboxes, and drop-down menus in a logical sequence. Pressing Shift + Tab moves the focus to the previous option or control. The Tab key helps improve the accessibility and efficiency of navigation, especially when using the keyboard instead of a mouse.

Information Booster:

•        The Tab key is widely used in operating systems, applications, and web interfaces to enhance keyboard navigation.

•        Shift + Tab allows users to navigate backward, providing better control over the focus flow.

•        In dialog boxes, the focus usually starts at the first interactive element (such as the first button or text box).

•        The Tab key is also used in text fields to move between form fields or control elements in a program.

•        The sequence of navigation through dialog boxes is typically predefined to make logical sense for ease of use.

•        In web development, the Tab key plays an important role in ensuring that web pages are navigable for keyboard-only users, which is crucial for accessibility.

Additional Information:

• The incorrect options:
• (a) To go back to the previous option or control: This would be done using Shift + Tab, not just the Tab key alone.
• (b) To close the current dialog box or menu: Closing a dialog box is typically done by pressing Esc or clicking the close button, not by the Tab key.
• (d) To select the currently highlighted option: The Enter or Spacebar key is usually used to select an option, not the Tab key.
