Copying steps of a ladder can be useful when you're performing the same step in different branches. To copy ladder steps, click the Copy Steps button in the bottom left of the page. You'll enter a view that has checkboxes to the left of each step. Select which steps you want to copy. Note that you can only select steps that are next to each other.
After you've selected your step(s), click Paste in the bottom right. You'll see an option on each branch (where the exit is) to Paste Here. Select where you want to paste the step and you'll see the steps you previously selected get copied over.
