Of course Rick, but that is not really calling another action from an action, since you need to use another event.
As Rod points out, preparing carefully advanced actions by choosing the right events, variables (reusing them) and the proper sequence for statements and decisions in advanced actions can solve a lot of situations. I have been trying to explain that in several blog posts. That was also the reason why I asked about more details concerning the user's situation. It is about an On Enter action. Until now I rarely had to use a workaround by navigating to a dummy slide to execute an advanced action over there using its slide events. All depends on planning and preparing.
