I'm trying to do this. In the upper left of the BASH window, there is an option called Edit.
Highlight the text. Go to Edit. Select Copy. Then go to the html page and select paste.
Just using Control-C or Control-Shift C to paste doesn't work. You have to use the drop down from Edit. This is true for my PC-BSD box and Fedora 8.
Who knows? This might help someone.
