VIMKiller is a button on-top of an arduino wrapped in a 3-D printed enclosure. It is expertly crafted. When the button is pressed it sends a message over your serial port to kill VIM. Now, at this point, you need to have the Julia VIMKiller script running in the background. It may be best to have this script run at start-up (easy-fix). The Julia script listens for this serial message and returns in kind by killing all VIM processes on your Linux machine. Easy, and practical — right?
