A new formatChord system renders keyboard shortcuts with platform-aware formatting. Supports three display styles: default (e.g., ctrl+A), compact (e.g., ^a), and symbol (e.g., ⌃A). Mac-specific glyphs (⌘, ⌥) are used when the platform is macOS. Chord sequences and arrow key groups are formatted intelligently.
