# How to Link

## OLab annotations

{% hint style="info" %}
The Annotation field no longer works the same way in OLab4.5 and its function has been deprecated for now. Instead, we encourage you to explore the concept of Role-Based Node Access (RBNA) which has much greater potential. 

See <https://olab.ca/role-based-node-access-in-olab4/>&#x20;
{% endhint %}

DEPRECATED: Some notes on how to share such materials using Annotation fields and Scoped Objects. \

## GitBook headings and sections

Also some notes on how to link within, and into, GitBooks headings. Note that you must use the **generated** heading from the ToC on the right, of the **rendered** version, not the one that you are editing.&#x20;
