Security 51 Keyboard and Mouse Controls

Keyboard and mouse is the reference input for Security 51 on Steam. Alawar’s checkpoint UI expects you to grab passports, slam them beside facility passes, and jab elevator buttons while visitors queue — speed without misclicks saves sanity documented in Sanity and Supplies. This page documents default PC bindings and workflow habits; exact key labels may appear in in-game settings or tutorials after launch.

Pair this guide with Document Verification while learning drag paths, and with Controller if you compare gamepad alternatives.

Desk workflow overview

Typical mouse targets:

• Document slots — passport, pass, medical certs, comparison record
• Tool buttons — X-ray, fingerprint, blood test when unlocked per X-Ray Scanning and Fingerprint and Blood Tests
• Action buttons — allow, deny, quarantine, call guards from Quarantine Protocol
• Elevator panel — send car, open doors, confirm headcount per Elevator Headcount
• Camera feeds — cycle angles when verifying cabin occupancy

Left-click drags papers; right-click or secondary actions may rotate or dismiss depending on tutorial prompts. Complete the in-game tool tutorials during Getting Started before rebinding anything.

Recommended hand rhythm

1. Middle mouse or scroll to zoom faces for Spotting Anomalies without leaning into the monitor.
2. Drag passport to record window — compare name and ID number first.
3. Drag pass — compare clearance and time window.
4. Trigger tools only when bulletins demand — avoid scanning everyone against X-Ray Scanning advice.
5. Elevator command only after checklist complete — use Verification Checklist mentally.

Keyboard shortcuts

Security 51 may expose hotkeys for tools and menus in settings. Until official docs list every key, prioritize:

• Start Day / shift controls — confirm before visitors arrive
• Tool toggle keys — switch X-ray or biometrics without hunting UI
• Camera cycle — verify elevator occupancy quickly during headcount beats

After Launch Patch Notes mention new bindings, update this wiki section. Playtest patch v0.0.1.105 extended shift length — keyboard efficiency matters more on long days from Early Shifts Walkthrough.

macOS and trackpad notes

Steam macOS builds sometimes map secondary click to Control+click. If drag-release fails on trackpads, use an external mouse for learning weeks. Full-screen mode reduces accidental menu bar focus when clicking top screen edges.

Versus controller

Controller trades pixel precision for comfort. Mouse remains faster for photo compares and small ID fields. Hybrid play — mouse plus keyboard numpad for elevator — is unsupported officially but some players map Steam Input creatively; test in demo first via Demo vs Full Game.

Practice drills

Run three demo shifts focusing only on input:

• Day A — documents only, no tool keys
• Day B — add X-ray when unlocked
• Day C — full stack with quarantine key

Compare mistake rates against Security 51 Review difficulty expectations. Input fluency is free performance — no promo codes needed, only repetition.

Keyboard and mouse will carry most wiki readers through Endings hunts. Keep hands on home positions, drag deliberately, and let the elevator wait until your fingers catch up to your judgment.
