If you are on Linux and still using the CapsLock key for it intended use, you may need to re-think your life choices. I have recently done just that and have remapped this near worthless key to Ctrl and it has been heavenly (apart from still wanting to press Ctrl of course).

If you are on Ubuntu you can remap it by editing the /etc/default/keyboard file. Find the line that looks like this XKBOPTIONS="" and make it looke like this instead: XKBOPTIONS="ctrl:swapcaps". This will swap the role of ctrl and caps lock. If you just want to kill the idea of CapsLock all together then you should use the ctrl:nocaps option instead.
