Copy/pasting from Safari

[Chris Gilland Desktop]

I am trying to figure out how to copy text from a web site to paste into 
safari.  Basicly, i had an edit field on the page, which had text in it.  I 
just needed to actually copy the content of what was in that edit field.  I 
interacted with the text edit field, but then when I do command+A, it seems 
to select all on the whole web page.  Also, when I click in the text box:  I 
say click, as I do not use cursor tracking when in Safari, I figured it 
already had all highlighted and selected in that box, but when I hit 
command+C, then went over to mail, to paste it into the body of an e-mail 
message, it wound up pasting the entire content of that web site I was on, 
rather than pasting just! what was in that edit text area.  Remember:  Yes, 
I did interact with the text area first, like I said.

So, what exactly am I doowen wrong?
Chris.
