Links and source nodes
======================
When creating links, smartLink will add some knobs to the nodes. Let's create
a link for one or our Read nodes in our current Nuke script as described in
the `previous <main_window.html#inserting-links>`_ section and then let's have
a look at what gets added to our nodes.

The source node
---------------
As soon as you create a link, your source node gains a new tab called **link**.
This tab contains two buttons that let you cycle between the source node's links:

    - **previous:** Clicking jumps to the previous link.
    - **next:** Clicking jumps to the next link.

.. note::

    You can use the hotkey **Ctrl + Arrow Right/ Left** (Linux/ Windows) or
    **cmd + Arrow Right/ Left** (Mac) to cycle your links.

The link node
-------------
Your link node includes a custom tab called **link**. This tab contains two buttons:

    - **jump to source:** Clicking jumps to the link's source node.
    - **connect to source:** Clicking connects the link to its source node in case you disconnect the link from the source node.

    You can use the hotkey **Ctrl + Arrow Up** (Linux/ Windows) or
    **cmd + Arrow Up** (Mac) to jump to the link's source node.
