One key that always gets in the way for me on any keyboard I use is the caps lock key. On Windows 7 I use a third party application to disable the caps lock key as noted in this article. On Mac OSX the functionality to disable the caps lock key is built in so it doesn’t require any third party software. Use the information below to disable the caps lock key on your Macbook laptop or other computers running OSX. I believe the functionality to disable the caps lock key was added in OSX 10.4 and I can confirm that it is still available in OSX Lion or OSX 10.7.1.
