I've opened this tread because i think that this action is just annoying and not good. In the article not only the caps-lock but also the num-lock and the print screen button are subject of the meaning of the author that the're useless.
My opinion is that a key as numlock is usefull: sometimes you want to use the numeric keys on the right of you're keyboard (the author is complaining that you've got to press the space bar to get numbers, with the numlock you don't :-) ) and sometimes you want the arrowkey's with the page up/down, home and end. This is why we want a numlock key.
The print screen button is usefull to (it's in the name) print the screen to a image. The most print screen buttons have 3 functions so why bother?
Last but not least: the Caps Lock, very usefull when you need to type a lot of capitals so you don't have to press shift all the time (same reason as with the numbers?) The printing of capitals isn't shouting (as the header in the page you're visiting is) but just to make things more recognizable to people (with capitals you can make a word in a large number of sentence more easy to find).
So why bother to a caps lock, num lock, scroll lock (what's that for ;-) ), print screen, function keys, the escape key, an insert button and a
open menu key (you know the key between you're right alt and ctrl key) who's using that one?
