format painter

Explanation:

Format Painter is a tool that copies formatting (like colors, borders, effects) from one object and applies it to others quickly. The Format dialog box and Fill options involve more steps. The Shape Styles gallery applies predefined styles but may not be as quick as directly copying existing formatting. Format Painter allows for instant replication of formatting from one shape to multiple shapes with just a click (or double - click for multiple applications).

Format Painter
