I have a confession: I hate the caps lock key! I mean it's a crazy holdover from typewriter days and for me at least it's always much more of an annoyance than a help. Fortunately, as we covered in an earlier Mac 101, Apple makes it easy to turn the caps lock key off altogether in the Keyboard tab of the Keyboard & Mouse Preference Pane. It looks like they've gone even farther with the new Apple Keyboard.
"Wolf" Rentzsch has discovered an undocumented anti-caps lock function whereby the keyboard will not register a very quick press of the caps lock as sometimes happens by accident when reaching for the left shift key. You can still activate it by pressing and holding the key. Rentzsch notes that if caps lock is already active a quick press will disable it, confirming that this is an intentional feature. He posts a little video to demonstrate.
This is vintage Apple: thinking about and implementing the little things that make your computing life just a little better.
