Beneath the Entity Palette is the Run View which allows you to run transforms and machines. Running a transform from the Run View is the same process as running one from the context menu and it will not be repeated here.
Expanding the Machines heading (+) shows all the machines that are available to run on the current entity selection on the graph.
Each of the line items display the Machine’s name and the start of their description. Hovering over the Machine name will display the full description for the machine. On the right-hand side of each item there are three icons. The star icon will add the Machine to the favorites category making it easier to find this machine in the future. Clicking the configure icon will open a window with the script that makes up the Machine. Finally, clicking the single arrow icon (>) will start running the Machine.
