# Slugs

In Kumu, a **slug** is a piece of text that has had all letters converted to lowercase, all special characters removed, and all spaces replaced with hyphens. Kumu uses slugs in many different places:

* In the URL bar
* Inside of [selectors](https://docs.kumu.io/guides/selectors)
* In [Markdown](https://docs.kumu.io/guides/profiles/markdown)
* In the [Advanced Editor](https://docs.kumu.io/overview/user-interfaces/view-editors#advanced-editor)

Knowing how to recognize, read, and write slugs is a skill that will come in handy, especially if you work in the Advanced Editor! Here are some sample slugs:
