# Can I copy and paste?

I have a $6\times 6$ matrix in a comment that I wrote. I wanted to copy it and paste it into a new question.

But apparently that can't be done. After I post a comment, I can't click on "edit" unless, apparently, I do it within a few seconds, so I can't copy the TeX code. And copying the rendered version doesn't give me the TeX code.

But in Wikipedia articles, I can copy the rendered version and then paste, and what gets pasted is the TeX code.

Is there some way to overcome this and copy-and-paste?

• If you're at the point where you're writing $6 \times 6$ matrices, you should be taking the conversation out of the comments already... – Qiaochu Yuan Jul 27 '11 at 20:14
• "I can't click on edit unless, apparently, I do it within a few seconds" The number of seconds is 5*60 = 300. – Willie Wong Jul 28 '11 at 2:25

Yes. Rightclick the TeX code, such as $\int _{\alpha} ^\beta f(x) \mathrm{d} x$. There is the option to "show the source" - at least in Firefox. Open this, and it will show the TeX code. Copy this, put it in its own special set of \$\$ marks, and you have duplicated the TeX.
