It is extremely time consuming to start the entire simulation after making modifications to a single component, especially when working with a large number of input records in a project that consists of dozens of components. On the other hand, it can be frustrating to single-step through a large project when you are interested only in simulating a component somewhere in the middle of a complex simulation flow. The commands Step through and Start through provide an effective way of multi-stepping a project to your point of interest.
