HOW TO DISABLE THE CAPS LOCK KEY
How many times have you gotten an email that was all written in caps? How many employees at your company think that it is acceptable. How about you do yourself and the world a favor by disabling the CAPS LOCK key!
- Click Start->Run and the type regedit and then press enter
- Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout - Add a new string value and name it: Scancode Map
- Add the following data to the Scancode Map:
00000000 00000000 02000000 00003A00 00000000 - You have to reboot your computer for the changes to take effect.
To re-enable the caps lock key just remove the Scancode Map and give your computer a reboot. [Thanks for the tip TL]

And what about re-enabling it? Can’t some sort of icon be created to enable this easily?
Dont forget to backup your registry. If you break it you buy it.
I highly recommend to remap the Caps Lock to the backspace key. Check out http://www.colemak.com for an ergonomic keyboard layout with Caps Lock remapped to backspace.
when iw as younger i jsut removed the caps key from my keyboard.. it was a lot easyer then this
I don’t understand how people can write an entire e-mail in caps. If it is more than one line, it just says they are lazy, because if it is more than one line people should notice it.
Any recommendations for doing this on OSX?
Seth, if you download DoubeCommand I believe you can turn the Caps Lock key into a CTRL key. That seems like it would get a little more use.
Seth, fKeys does the same, this is the one I use.
thanks derek and padde
In OSX, just go to System Preferences, Keyboard & Mouse, then in the Keyboard Tab click Modifier Keys. Set the Caps Lock to No Action and it’s disabled. (that’s the steps for Tiger, in Panther there is a freeware program called uControl that lets you disable it, and I imagine the steps for Leopard are similar to Tiger)
Um, By any chance is it safe, or can it kill my desktop?
