**ACTION TASK**
To define the type of task, Vtenext provides symbols that can be used to indicate the action performed by each task.
These symbols can be selected during the diagram editing mode by pressing on the task and then later on the wrench that appears among the various selectable options.

It is important to point out that these symbols do not go to affect the behavior of individual tasks, as their purpose is simply to show an initial visual reference that can facilitate the interpretation of individual tasks. Thus, it will be at the user's discretion to select the symbol most appropriate to the action performed by any given task.
Once selected, each symbol will be placed at the top left of the task and will be visible during process configuration.
Below is an example for each selectable type:
**Script Task**
