I found the following html and JavaScript on JSFiddle.

What code is needed to make this work in an html file I would create using notepad?

The code expands text from an abbreviation into full text.

html section:

<textarea id="comment" rows="20" cols="30"></textarea>

JavaScript Section:

shortcuts = {
    "cci": "customer called in",
        "rfc": "request for comments",
        "www": "world wide web"

window.onload = function () {
    var ta = document.getElementById("comment");
    var timer = 0;
    var re = new RegExp("\\b(" + Object.keys(shortcuts).join("|") + ")\\b", "g");

    update = function () {
        ta.value = ta.value.replace(re, function ($0, $1) {
            return shortcuts[$1.toLowerCase()];

    ta.onkeydown = function () {
        timer = setTimeout(update, 200);
