# Key Browser

## Fold level

There is a convention that we use the separator `:` in the key name to represent property relationships. For example, a key with name `users:4590:name` can be a key that stores the user name of the user whose id is 4590.

Medis supports this convention out-of-box by making the name parts as the folder of the tree view:

![](/files/KUT0bJf2KNuBOGMU5yYU)

By default, we only show the first part as folders. However, you can configure this on the preference window: 

<img src="/files/45qhwYfN70qrbK2nEVAi" alt="" data-size="original">

In the screenshot above, we set the "Max fold level" to 3, and the key list will look like:

![](/files/Hs79aQufcj7Ak9H8B9LH)
