Lefty v1

Lefty v2 — Remap any key for left-handed gaming.

What it does:

• Remap any key to any other (e.g., WASD → IJKL, O→W, K→A) for left-handed play
• Works in any game via low-level Windows hook (WH_KEYBOARD_LL)
• Very low latency: 0.02ms Rust engine (0.5ms with Interception driver)
• System tray support (close to tray, F6 toggle)

Profiles:

• Sycho — OÑLK (O=W, K=A, L=S, Ñ=D mirrored)
• Left-handed IJKL (W→I, A→J, S→K, D→L)
• Arrow Keys, Custom, Disabled

How it works:

1. Pick a profile on the left
2. Add/Capture a mapping (e.g., ' → 1)
3. Activate (or F6)
4. Play — hook uses SendInput with wVk/wScan and suppresses original with return 1
5. Pause/F6 to restore, close to tray

Install:

• Portable: dist/Lefty.exe
• Installer: dist/Lefty_1.1.0_x64-setup.exe / .msi
• Run as Administrator for elevated games

Tech: Rust + Tauri + React, Windows hook, no GIL, TIME_CRITICAL.
