// which has an excellent implementation. While gocui handles things like text highlighting
// and the layout of the text areas -- also things like handling SIGWINCH and lots of really
// complicated console handling, it sends events here in a clean way.
// This is equivalent to the linux command xev (apt install x11-utils)
