If you've longed for more flexibility than the simple on/off method most input control/tyke-blocker programs offer, Kid-Key-Lock gives you finer control over keyboard and mouse use. Unlike the keyboard lockers we've previously covered, Kid-Key-Lock has degrees of lockout. You could, for instance, use Kid-Key-Lock to lock out system key combinations to prevent your little ones (or your own little fingers) accidentally booting out of a game or important app again. Alternately, you can lock the keyboard to just let in letters, numbers, or spaces to help a young typist learn the basics. The mouse can be locked with a similar range of finesse, with individual buttons, the scroll wheel, and double clicking allowed or halted. Kid-Key-Lock is freeware, Windows only.
