# Layer variables
You can see all Layer variables if you double click on a layer. In the window that opens, Layer variables will be visible on the right hand side.
Most of *Layer variables* are also visible under the *Layer variables* collapsible of the *Layer properties*.
{% hint style="info" %}
**Good to know**: to keep Layer Properties clean and neat, you can hide some Layer Variables so that they do not appear in the Properties window.
{% endhint %}
Every layer has a few predetermined Layer variables, that define the characteristics of the layer itself. These variables are in **General** and **DMX** Variable groups and cannot be deleted.
