Input Device Tests
Input tests cover keyboard maps, multi-key ghosting with peak simultaneous count, a short typing check, and mouse or trackpad drills for buttons, pointer event rate, wheel, drag, and visual delay.
Start with Keyboard Test or Mouse Test for everyday smoke checks. Use Ghosting when chords drop keys, and the specialized mouse tools when a single symptom needs a sharper lens.
