Description:
reminds you to take a break from typing
xwrits helps you prevent repetitive stress injury. . xwrits is a small reminder program designed to let you know it is time to take a break from typing to rest your wrists and prevent any damage to your wrists (or at least make them feel better if you've already damaged them). Normally works on the honor system, but if you find yourself unable to stop typing during your break, it can also lock your keyboard.
