Toddler Keys is a tool for locking your keyboard. This kind of utility is very useful for parents who would not like that their children touch their computers. When someone presses a key, sounds and pictures will be displayed, but your desktop cannot be accessed. The purpose is to entertain the child while protecting your data. Of course, it is possible to customize sounds and pictures. To close the program, just type the word “Quit”. The only problem is that Toddler Keys only supports Windows XP.
