Just wanted to add how to copy and paste in case thats unknown as well.

After you click the disk and highlight the chat in the window that pops up, either right click and select "copy" from the drop down menu, or for a shortcut, press the Ctrl key and the C key. So hold down the Ctrl button and then press C. That saves it.

Then go to a pm to a mod or open a text document and right click and select "paste" from the drop down menu, or for the shortcut, hold the Ctrl button again and press the V button.

The key to copying is the highlighting, so make sure all the text is highlighted before copying. You can practice this in a text document, just type something and highlight it, and practice copying and pasting. You can practice in PM too if you don't want to open a text file.
