I rarely ever find a need for CAPS lock. After getting fed up with having to take my hand off the mouse constantly to hit enter, I got the idea to remap the CAPS key to ENTER. I found that it made my life much easier and streamlined my typing. Remapping keys is pretty simple and can be done in two commands.
setxkbmap -option caps:none xmodmap -e "keycode 66 = Linefeed"
