When you like neatly created lessons, you can copy and paste repeating items onto new slides.
For example, if you are using covers on the same position on multiple slides you can copy them over from one slide to another. To achieve this, follow these steps:
Select your covers (select multiple by holding the Shift-key).
Click Crtl + C (or Cmd + C on Mac).
Navigate to another slide.
Click Crtl + V (or Cmd + V on Mac).
