# Action
Action steps can be used for **participatory and automatic actions** in self-paced exercises.
### 1. Comparison
**Compares data** which decides what information will be sent out next. 🎓 E.g. different content could be sent out dependent on player score.
### 2. Timer
**Creates** **a delay** before publication of the attached steps. Use the timer to publish other content outside the primary channel to create a sense of realism when an immediate reaction would seem unusual.

### 3. Erase all
**Deletes all messages** for player clicking the button. 🎓 E.g. use if a player doesn't get enough answers right on a quiz and needs to retake.
