Any changes you make here are temporary and are lost when you close down. Changes to line numbering and tooltip evaluation apply to the current Code window and do not persist to any new Code windows that you create. However, enabling text coloring or changing the default tab size or character width (for Shift Lines Left and Shift Lines Right) applies to the current Code window and to any new Code windows in the current session.
