[TxMt] editing css

[Andreas Wahlin]

When editing CSS (and possibly, other things as well) I find myself  
wanting to invert command+return behaviour.
At least here, command+return will hop to a new line without breaking  
my current line at the caret, while return will hop to a new line  
taking with it all the contents right of the caret (like always). I'd  
like to invert this somehow.
Also, I totally love how typing : in css gives you the smart ;  
ending, but I'd like a space after the : as well, how?

thanks
Andreas
