This is one of those features within the Microsoft Office family that I use a lot.
Scenario: If you have formatted a Letter, Word, Sentence or a Paragraph with lots of different formatting types like, change of fonts, colors, bold, italics, underline, alignment, etc. which needs a lot of clicks and if you want to apply the same formatting to another letter, word, sentence or paragraph in the same document, you do not have to redo everything again.
Simply, select part of the text from which you want to copy the formatting from and click on the “Format Painter” button within the clipboard group under the Home tab. Select the destination text and the formatting will be applied.
If you need to apply the formatting on to no consecutive, multiple places in the same document, double click on the Format Painter button and you can apply any where in the document.
