Need four swipes of the sword at .56 second intervals, and need to do this with one key? With repeat tuner you can adjust the repeat key of your keyboard FOR EVERY KEY. Customize your keyboard by setting repeat frequency (number of milliseconds between each repeat), repeat delay (how long a key should be held before repeat starts) and repeat count (how many times to repeat before stopping).
Press and hold "A" for more than 200ms - it will repeat every 100ms up to 25 times.
