BRYTER allows a free-hand navigation in the Node graph. You can click and drag on an empty space, which allows you to move the whole canvas. If you are using a mouse, using the scroll wheel will move the canvas up and down like a web-page and holding the SHIFT button on your keyboard will allow you to scroll horizontally. If you are working with a touchpad, you can move your page using two fingers like you would also scroll a web-page.
Furthermore, you can zoom in and out using the plus and minus buttons in the bottom left corner. Clicking the center button between the plus and minus buttons will move your module to the beginning, allowing you easy navigation.
If you are looking for a specific node or want to jump to a certain part of your graph, consider using the Search option at the top of your graph window or the Module overview. If you know the title or label of the node, use Search. If you are only aware of the type of node (result, input, action, value), filtering in the Module Overview should help with finding and navigating to the correct node easily: simply click on the row containing the desired node and the WYSIWYG sidebar will open up or go back to the graph view by closing the module overview to jump to the selected node.
