Keyboard shortcuts

Is there a comprehensive list of mouse/keyboard shortcuts for SpaceChem?

I read somewhere than you could change the priority of bonders using ctrl+scroll wheel. I would be especially interested in a shortcut to instantly place a bond+ instead of bond+/- and then having to right-click to change it.


Let's start something :

  • undo: crtl + Z

  • redo: crtl + Y

  • select speed: number keys 1, 2, 3, 4

  • stop: ~

  • pause : space

  • select : shift + mouse

  • copy : ctrl + drag mouse

  • enables/disables the ctrl actions in boss levels : F1F2F3F4

  • debug mode : F5

  • delete selected symbols : Del
