Panning while dragging

  • When dragging a node to move it in the network editor, you can automatically pan by holding the mouse near the edge of the network view without

  • Hold Space while dragging to lock the cursor inside the network view. This lets you drag large distances with autoscroll, without worrying about the mouse pointer going outside the view.

Network overview

The overview shows a small schematic view of the overall network in the bottom left corner of the network view. It lets you see where the current view is in relation to the overall network, and lets you quickly move the view by clicking in the overview.

You can control when the overview appears using the Tools ▸ Show overview menu items:

When needed

The overview only appears when the entire network doesn’t fit in the view.


Always show the overview.


Don’t show the overview.

By default, the overview is set to show “when needed”.


“Quick marks” let you quickly set and return to lightweight, disposable network location “bookmarks”. Unlike regular bookmarks (see below), you can use them as-needed and then override them or forget about them. They are not saved with the scene file.

Each mark records the network path, view location, and zoom level. So you can use marks to switch back and forth between two different networks, or two different areas or nodes in the same network.

To...Do this

Set a quick mark

Press ⌃ Ctrl and 1, 2, 3, 4, or 5.

On Mac, press and 1, 2, 3, 4, or 5.

Return to a quick mark

Press 1, 2, 3, 4, or 5.

Go back to the previous view

Press ` (backtick).

This lets you quickly switch back and forth between two views, possibly in different networks.

Location history and bookmarks

To...Do this

Go the previous or next network location viewed (like a browser)

  • Use the arrow buttons in the network editor toolbar.

  • Press Alt + or Alt + .

Use bookmarks

Click the history dropdown menu at the end of the path gadget at the top of the editor pane, and choose Bookmarks. You can use this menu to add new ones or edit existing ones. Once you add a bookmark it will appear in the history dropdown menu.

These bookmarks are saved with the scene file, so you can use them to make a list commonly useful locations always available.
