Which command would you use to copy an animation effect to another shape?

The Animation Painter is the correct choice for copying an animation effect from one shape to another in PowerPoint. This tool functions similarly to the Format Painter, but it is specifically designed for transferring animation settings rather than formatting properties like font size or color. By using the Animation Painter, you can easily replicate animation effects such as fade-ins, slide-ins, or other effects applied to a shape, streamlining the process of applying the same animations to multiple elements within your presentation.

The other options refer to different functionalities. The Format Painter is exclusively for copying formatting attributes, such as font styles and colors, not animations. Copy Animation Action isn't a defined feature in PowerPoint; thus, it doesn't serve as a tool for copying animations. Lastly, the Slide Animation Tool does not exist as a standard command in PowerPoint and could lead to confusion regarding its effectiveness or purpose. Therefore, the Animation Painter stands out as the most appropriate tool for the task outlined in the question.
