Default Lexicon Event Descriptions

Lexicon enables you to add descriptions to Events, empowering everyone to understand and use the right data to find quick insights. Event Descriptions help your entire team understand what your data means, so everyone stays on the same page. Below are the built-in definitions for events created by Mixpanel.
