Hello, I was messing around and removed the "configure desktop" option from the context menu. How do I get back to this menu? This settings page seems to not be found within system settings. Very frustrating, please let me know if you have any ideas.

Left-click on the toolbox icon and choose "Configure Desktop" there.
On the "Mouse Actions" page you should be able to enable/disable entries in the right-click context menu by clicking on the configure button for the right mouse button action (which should be set to show the context menu).

Thank you but the toolbox is disabled, and also within that configuration menu. Appreciate your response though. I figured out that the keybind alt+D or alt+S brings up the menu!

Take care.
