+- "Control" or "Ctrl" for the Control key  
+- "Shift" for the Shift key
+- "Alt", "Opt", or "Option" for the Alt key (Option on macOS/iOS)
+- "Super", "Cmd", "Command", "Win", or "Windows" for the Super/Windows key (Command on macOS/iOS)

+Traditionally, due to conflicts with system keybinds, Geometry Dash on macOS assigns the same actions to Control and Command modifiers. This can be accomplished for any mod through per-platform default values.
