Which feature is a small rectangular pop-up window that displays a brief description when you hover over a control?

• A. Tool tip
• B. Help bar
• C. Task bar
• D. Dialog box

Answer: (A)

A tooltip is a small rectangular pop-up window that shows a brief description when you hover over a control. This behavior gives quick, contextual hints about what a button or icon does without opening a new window or interrupting what you’re doing. Tooltips usually appear after a short delay and disappear when you move the cursor away (and they can also appear when a control gains keyboard focus for accessibility). The other options don’t fit this pattern: a help bar would present longer help content in a different part of the interface, a task bar is the strip that shows open applications, and a dialog box is a separate window that requires user interaction.
