- Arrow Keys = choose side (up/right/down/left)
- You will see overlapping red/cyan circular dot fields. With fusion, a single target appears in depth from binocular disparity (not a drawn outline).
- Space = cannot see target, score -1 and refresh
- P = pause/resume session. Exiting fullscreen with Esc pauses automatically.
- Core Settings (in order): Vergence Mode, Visual Preset, Session Target, and Session Minutes define the session profile.
