Is there a way to build a surge electorlyzer without a number pad? My laptop does not have a number pad. I've tried all kinds of general utilities to emulate a number pad but I can't get it to work. Thanks!

Ah, A kind discord user answered my question for me. Thanks @Eggplantade!

There is a section in settings -> controls -> nullius for the bind. I had gone to the controls screen and tried changing other bindings but I had never realized there was a nullius specific section there. Thanks for the fun mod!

Yes, every mod that adds key binds can be remapped in their own section. The Bob's Logistic keybind for inserter length is another one to take note of, since that's the primary way to get long inserters in Nullius (once you research the tech for it, or there's also a panel on the upper left you can use).
