How to paste content of a variable to clipboard in SC 2 in Twine 2

I am using Sugarcube 2 in Twine 2.

I would like the user to paste a blob of text generated in a passage onto the clipboard so that he/she can save it as per their choice (email, in a word document, etc.)
How can I save value of a variable to system clipboard?

Additionally, how can i give an email button, which when clicked opens up local email client and populates basic fields (to, cc, subject, and body). This way user can easily share results with others.

Thanks in advance for your inputs.
