I use the terminal a lot be it in Mac, Windows or Linux. And it's kinda frustrating in Mac for the lack of a dedicated insert key. Clearly, you'll never think about small things until it's gone. Copy-Paste function turned out to be an important feature.
So I looked for the equivalent command/key combination in the net and the combo below worked on MacBook Pro.
Yeah, I know it's a kinda bummer because it's just one key on PC( Windows, Unix and Linux). But that's how Apple is. Also, I'm not sure if it works for iMac. I heard there's another key combination.
