Twitter: delete a retweet or undo a retweet !!!

Holy twitter!!! I had accidentally retweeted one post. How do you remove that retweet from my profile. Twitter has a confusing UI. And my Google search took more than few clicks to the top pages to final get the trouble shoot.
As easy as retweeting and exactly opposite !!!
Just press on retweet again on the tweet you have retweeted. Magic, you get the option to undo the retweet as below.
I cracked it and hopefully many you also will be able to do it swiftly.
