Learning IE - F12 key opens Developer Tools

I have been working with Internet Explorer (version 8) because my company still mandates that Developers test in IE8 since our customers mainly use IE8.

Well, sometimes we developers run into issues and I struggle to figure out what the issue is when the app works fine in FireFox or Chrome. Today, I accidentally stumble on this cool trick.

Open Internet Explorer.

Press key F12 and viola! the IE Developer Tools window opens.

Not sure how useful this is, but now we know it exists! (Instead of wondering why IE doesn't have one like FireFox and Chrome, lol.)
