7) Take a few steps back

In the Expert view, there are plenty of useful panels you can have up and visible while you’re working on images in Photoshop Elements: Open the Window menu to see what’s available. You can keep the effects or filters panels open at all times, for example, or see what layers make up your image, or keep an eye on the key details of an opened file.
One of the floating windows we find most useful is the History one. You’re probably aware of the Ctrl+Z (Windows) or Cmd+Z (macOS) shortcut that enables you to undo the last change you’ve made to a picture, but the History pane lets you go back dozens or even hundreds of steps—very handy if you’re not happy with the way your edits are turning out.
