Abstract: A system and methods for processing chord-based input sequences and managing context-aware command execution. A server receives and processes input from at least one client device. An input capture module receives keypress events from a human input device and filters input signals. A chord recognition module analyzes whether a keypress sequence constitutes a recognized chording pattern based on predefined rules, including modifier-based chording, simultaneous non-modifier keypresses, release-based execution, and time-based chording. A sheet management module assigns a command sheet based on the active application or computing context. A sheet stack manager prioritizes command sheets, with the highest-priority sheet determining execution when multiple layers are active. A command execution module processes system or application commands based on the recognized chording pattern.
