Several sites like Quora's comment section have this, where you can control-b text inside a editable div, and it becomes bold, or you can control-b and whatever you type afterwards is bold until you do control-b again.

I've tried replicating this, and I have seen one question about how to do this with a button on Stack, but have had no success attempting this with shortcuts (control-B).

Here's my attempt mostly based off the other question I mentioned, but it isn't working:


document.onkeyup = function(e) {
if (e.ctrlKey && e.which == 66) {


<div class="form-control" id="comment" contenteditable="true"></div>

I'm not very experienced when it comes to this usage of js, so I'm likely way off. Anyone have any ideo how this can be done?

You can enable bolding in editable divs as follows:

 // enable bolding

$(window).keydown(function(e) {

if (e.keyCode >= 65 && e.keyCode <= 90) {

    var char = (e.metaKey ? '⌘-' : '') + String.fromCharCode(e.keyCode)

    if (char == '⌘-B') {
