Closing as not planned.

Keyboard shortcuts add complexity and discoverability challenges. The existing command system (help, clear, save, copy, etc.) provides efficient interaction without requiring users to memorize shortcuts.

For a simple CLI chat interface, explicit commands are clearer and more maintainable than hidden keyboard shortcuts.
