How to select multiple steps in the workflow builder
Use Cmd + click on Mac or Ctrl + click on Windows and Linux to select several steps at once. Hold the key and click each step you want to include. Selected steps are highlighted on the canvas.
Copy, paste and duplicate a selection
With steps selected, use the standard copy and paste shortcuts to place a copy of the group anywhere on the canvas. You can also duplicate the selection. Connections between the selected steps are kept, so you do not need to rewire them. Connections to steps outside the selection are not, so wire the new group into the rest of your workflow after placing it.
