How do you pan the nodes viewer? What's the hotkeys to pan the node viewer on Linux, it's not listed in the settings or the docs?
Tried every combination of Alt, Shift, Contrl and Left or Right mouse button in the nodes panel.
There is an option to emulate the middle mouse button, you can enable it from the settings in the Input pane.
After enabling the middle mouse button emulation, you should be able to use Alt+Shift along with the left mouse button for panning the view.
