Aren't you worried about having the keyboard work one way in Emacs and 
another in other programs. Here is an explanation of the danger inherent 
in such a strategy:

I think it makes the anonymous lambda function act like a command.

Not with it's full initialization functionality, but many things (as in 
your example above) can be set up by pressing C-x C-e with the cursor 
after the last parenthesis of the lisp expression. The expression 
doesn't even have to be in .emacs but if it isn't saved saved there it 
won't be set the next time you start Emacs.
