Whereas “press and hold” is used toimply a key press of typically longer than 1.5 seconds.As an example: when using a computer keyboard to type a capital letter youwould “press and hold” the SHIF T key and “momentarily” depress theappropriate LETTER key.The “function” associated with key(s) pressed is executed on the keyRELEASE, not the key DEPRESS.
