Which tool adds keyframes to a clip's attributes?

• A. Pen Tool
• B. Hand Tool
• C. Type Tool
• D. Selection Tool

Answer: (A)

Keyframes let you animate a clip’s attributes over time, showing how values change from one moment to the next. The Pen Tool is used to add those keyframes directly on a property’s animation line, letting you place new keyframes at the exact times you want changes to occur. Once you’ve placed a keyframe, you can tweak the value at that point and move the keyframe along the timeline to shape how the change progresses, enabling precise motion and effect control. Other tools serve different tasks: the Hand Tool simply pans the view, the Type Tool adds text, and the Selection Tool moves or selects objects—none of which create new keyframes.
