If you’re like most people, you probably use Photoshop to create graphics and illustrations. But if you want to flip a selection horizontally, there’s a way to do it without any special software or tools. Just follow these simple steps:

  1. Choose the layer that you want to flip the selection on top of.
  2. Drag the selection up or down so that it covers the bottom of the layer (or as close to the bottom as possible).
  3. Hold down the Option key and click on the leftmost edge of the selection. This will cause Photoshop to flip the selection horizontally so that it is now on top of the layer below it.
