Useful when typing constant identifiers (Score 1)

I am a digital ASIC design engineer. For a while, this occupation hasn't been much different than that of a software designer -- we use languages such as Verilog or VHDL rather than C, Java, etc. A common convention for programmers in all of the aforementioned languages is that constants are all caps. My left pinkie is trained to hit the caps lock key when I type constants, then hit it again when I'm done. This definitely speeds up my typing.
