 # Implementation Plan: Fix `keys_down` AttributeError
 
 ## Phase 1: Investigation and Implementation
-- [ ] Task: Investigate ImGui API
-    - [ ] Identify the correct `imgui-bundle` equivalent for `io.keys_down` (e.g., `imgui.is_key_pressed(imgui.Key.r, False)`).
-    - [ ] Search the codebase for any other instances of `io.keys_down` that need updating.
-- [ ] Task: Apply Fixes
-    - [ ] Modify `src/gui_2.py` (around line 695) to replace `io.keys_down[ord('R')]` with the modern API call.
-    - [ ] Apply the same fix to any other locations found during the codebase search.
-- [ ] Task: Verification
-    - [ ] Start the application locally and trigger the `Ctrl+Alt+R` shortcut to confirm it no longer crashes.
-    - [ ] Ensure general application stability.
-- [ ] Task: Conductor - User Manual Verification 'Phase 1: Investigation and Implementation' (Protocol in workflow.md)
