The quotes are definitely not the way to go. I've tried
vim -u test_vimrc.vim
where test_vimrc.vim contained merely your first line (slightly
modified):
nnoremap <f3> :set nobackup<return>
and it worked fine. I don't know whether it has to do with
switching over to nnoremap (I prefer to be explicit when I
specify a mapping) or some other plugin that is overriding your
desired settings. You might try
:scriptnames
to see what scripts are being loaded (and may want to investigate
them in the event that one of them is rebinding <f3>).
-tim
