Feature Request: Combo key mapping support (e.g. KEY_A + KEY_B → action)

[alabulei1]

Summary

Support combo/chord key configurations, where pressing multiple keys
simultaneously triggers a specific action or command.

Motivation

Currently there is no native way to configure combo keys on the device.
Users have to rely on third-party software like Karabiner-Elements (macOS only)
as a workaround, which is platform-dependent and not ideal.

Proposed Solution

• Define combos via CLI or future browser-based UI
• Support simultaneous key press → mapped action
• Example: YOLO + CUSTOM → sends /batch

Workaround (Current)

macOS users can use Karabiner-Elements to configure combos at the OS level,
but this is not a native solution and doesn't work cross-platform.
