Feature Request: Context-Aware Shortcut State Machine (e.g., Display/Profile Based Hotkeys)

Description of the new feature / enhancement

Summary

Currently PowerToys Keyboard Manager only supports static, global remappings. This proposal adds a state machine layer that allows shortcuts to behave differently based on current context (e.g., active monitor, color profile, or user-defined state).

Proposed Behavior

1. State definition – Users can define custom states (e.g., "Monitor1 mode", "Monitor2 mode")
2. State switching – A dedicated shortcut can cycle through states
3. Conditional remapping – Shortcut mappings can be set to only work when a specific state is active
4. UI placement – This should live under an "Advanced / Experimental" section, off by default to avoid confusing casual users

Acceptance Criteria

· User can define 2-3 custom states
· A shortcut can cycle through states
· Shortcut mappings support state conditions
· Feature is off by default, behind an advanced toggle

Scenario when this would be used?

Use Case / Scenario

A concrete example:

· Same shortcut Ctrl+Win+Up:
· When Monitor A is active → adjust color temperature
· When Monitor B is active → toggle refresh rate

Another example:

· A "profile switch" shortcut cycles through 2-3 preset states (Gaming, Coding, Dark Room)
· Each state changes what other shortcuts do (e.g., brightness, volume, night light)

Supporting information

Additional Context

Keyboard Manager already supports app-specific remapping (targetApp). State-based remapping follows the same pattern — no changes needed to the low-level hooking logic, only the evaluation layer needs new conditions.

No files or tests are named. Start by reviewing Keyboard Manager's existing app-specific remapping and its targetApp evaluation, then determine how user-defined states, state switching, conditional mappings, and the advanced opt-in setting would fit together. Done means the acceptance criteria are implemented, including 2–3 states, cycling, conditional shortcuts, and an off-by-default toggle.
