Mapping to search Google Code

[Sean Hubbell]

Hello,

 I seem to be oblivious to what I am doing wrong. I have the following 
mapping I would like to execute from vim:

nmap <F2> :!"/usr/bin/firefox 
'http://www.google.com/codesearch?hl=en&q=+'<cword>"

I can execute the following from ex, but I am missing something from the 
mapping, does anyone have an ideas?

Thanks in advance,

Sean
