MacroGroup — Command ID Table (IDC_ constants)

Source File: include/cef_command_ids.h

Process / Thread Context: Compile-time only (macro definitions).

Purpose: Generated by make_pack_header.py. Defines 504 #define IDC_* numeric constants for browser command IDs (menu commands, context-menu commands, keyboard commands, bookmark-bar commands, etc.). Use cef_id_for_command_id_name() for version-safe lookups.
