Mathematica includes comprehensive, real-time, semantics-aware input annotation. It uses styling and coloring to provide immediate visual feedback on function names, variable scoping, argument structures, and other aspects of input typed into Mathematica--defining a major new level of clarity and sophistication in automatic code annotation.

• Full dynamic-function name dictionary, with as-you-type coloring.
• Automatic highlighting of local variables, with automatic-scope conflict detection.
• Annotation based on real-time semantic program analysis.
• User-definable syntax coloring.
• Full control of annotation styling.
• Automatic blocking of digits in long numbers, and automatic multiplication signs.
• Automatic dynamic protection mechanism for overly long outputs.
• .m package editor with dynamic function index interface.
