Source page / clipboard

Is it possible to copy the source page HTML of a web page to the clipboard?
I have tried ${KEY_CTRL+KEY_A} and ${KEY_CTRL+KEY_C} but that’s not what he does for me.

maybe sourceExtract or whatever

Thanks to those who can help

he rephrased the question. i need to extract innertext from this page

<div class="aa"><div class="xxa"><div id="ee">hello</div>home</div></div>

result must be:

<div class="xxa"><div id="ee">hello</div>home</div>`

thousand thanks
