Triggers are either joystick buttons, mouse buttons, or keyboard keys. When these triggers are pressed, the program will start capturing video, Auto Save, or Erase Film. Sometimes a joystick has a button mapped to the keyboard. If that is the case, one has to set that joystick's "trigger" in the keyboard trigger area found in the Trigger Setup window.

There are two types of triggers for capture.  The HOLD style trigger, and the TOGGLE style trigger.  The HOLD style only records while the trigger is pressed.  The TOGGLE style will toggle capture on and off.
