![panel 1: quitting a terminal program isn't always easy
person (thinking): "I pressed Ctrl-C 17 times and NOTHING HAPPENED"

Ctrl-D - if you're at a prompt in a REPL >>>
q - if it's a full screen program
Ctrl-\ - sometimes works if Ctrl-C doesn't
kill -9 - the last resort
panel 3: how Ctrl-D works
programs that read input will usually have some code like this:
text = read_line()
if (text == EOF) {
exit()
}
Ctrl-D is how you send an EOF to the program ("I'm done!")
important: Ctrl-D ONLY works if you press it on an empty line
panel 4: how Ctrl-C works *
