We all make mistakes from time to time. It's impossible to go back in time to correct your previous actions like they never existed… or is it? If you find yourself editing a document and realize you need to quickly undo or redo previous actions, do so with ease using this week's keyboard shortcuts.

In many applications - including Adobe and Microsoft - pressing Ctrl+Z (Cmd+Z in MacOS) undoes the last operation/action you performed. Conversely, you can redo the last operation/action performed by pressing Ctrl+Y (Cmd+Y in MacOS).
