# Workflow Editor Actions Panel
When editing a user flow, an "Actions" panel or toolbar provides quick access to various components and settings for building and managing your workflow.
This panel typically includes the following options:
**Add Trigger:**
* **Icon:** Lightning bolt
* **Description:** Allows you to set up or modify the initial condition(s) that will start the workflow. This defines how users enter the flow.
* **Use Case:** Defining if a flow starts based on a user action, a profile update, a schedule, or an API call. [See the adding triggers page for a more detailed break down. ](/userflux-docs/feature-guides/user-journeys/user-flows/adding-a-trigger.md)
**Add Step:**
* **Icon:** Stacked items / Drawer (looks like a filing cabinet drawer)
* **Description:** Enables you to introduce a new action or stage within the workflow. Steps are the individual tasks or processes the workflow executes after a trigger.
* **Use Case:** Adding actions like sending an email, updating a user profile, adding a delay, or tracking user events..
**Add AB Split:**
* **Icon:** Flask / Beaker
* **Description:** Allows you to divide users into different paths within the flow to test variations of a message, timing, or action (A/B testing).
* **Use Case:** Testing two different email subject lines to see which gets a higher open rate, or sending different offers to segments of users.
**Entry Criteria:**
* **Icon:** Entry arrow
* **Description:** Controls how often users can re-enter this specific workflow. This helps prevent users from being spammed or experiencing the same flow repeatedly in a short period.
* **Use Case:** Setting rules like "a user can only enter this welcome flow once" or "a user can re-enter this cart abandonment flow after 7 days if they abandon another cart."
**Exit Criteria:**
* **Icon:** Exit arrow
* **Description:** Defines the conditions under which users should be removed from the workflow, even if they haven't completed all the steps.
* **Use Case:** Removing a user from an onboarding flow if they complete a key activation event, or removing them from a promotional flow if they make a purchase.
Note that when you apply an entry / exit criteria through the actions panel it will apply to the whole workflow.
This is a critical distinction as you can also apply entry condition at a step level as well.
