Every so often, I have to type some text consisting mostly of uppercase letters, but with an occasional lowercase letter—essentially, sentence case, but inverted. On Windows, I would simply have caps lock on the entire time, and pressing Shift would give me a lowercase letter. On OS X, however, if caps lock is on, I only get uppercase letters, whether Shift is pressed or not.
So, I can either hold down Shift the entire time I'm typing, letting go of it briefly to type a lowercase letter, or press Caps Lock twice for each lowercase letter I type. Neither works as well as what Windows does.
Is there a way to get Caps Lock to behave as it does on Windows, where pressing Shift while caps lock is on produces lowercase letters?
I am running 10.6.
