Current Web Page (Paste) & Current Selected text

[Chris Cairns]

I have recently switched to Firefox. What do Firefox users do to use  
Current Web Page(Paste)? (dont tell me to use OmniWeb)
Secondly, what do you do to grab selected text from applications like  
Firefox into QS command window just like Cmd+Esc is used in other apps  
(cocoa apps, i think)?
