Simple copy paste function in JavaScript which supports Chrome and Mozilla as well

I am making a simple Edi开发者_高级运维tor. So I want Simple Copy and Paste Function which can support Google Chrome Browser and Mozilla as well

You better sit down for this:

• Copying: CTRL + C
• Pasting: CTRL + V

Works great in most browsers, but not on Mac as they don't have the same CTRL key like PC users. Mac users have the CMD key for that.

For Mac users:

• Copying: CMD + C
• Pasting: CMD + V
