Test Multi-Key Combinations for Anti-Ghosting

Hold down W + A + Shift + Spacebar simultaneously in the Keyboard Ghosting Test to verify whether your keyboard supports N-Key Rollover without dropped inputs.

Calibrate Analog Stick Deadzones Hands-Free

When checking a PS5 or Xbox controller for stick drift, flick both thumbsticks gently and let them snap back to rest without touching them for 5 seconds.
