Key Acceptance Delay

A keyboard accessibility setting that requires a key to be held down for a specified minimum duration before it is registered as a deliberate press. Keys released before the delay period expires are ignored, filtering out brief accidental touches. Key acceptance delay is the mechanism behind the SlowKeys accessibility feature available in most operating systems. While effective at reducing accidental key presses for users with tremor or poor motor control, acceptance delay slows overall typing speed because every intended keystroke must be held for the full delay period. The optimal delay setting varies by individual and involves a trade-off between filtering accuracy and typing speed.
