I've not seen this behaviour. I noticed that you are not running the  
latest version of R though - you might try upgrading (R 2.8.0 GUI 1.26  
(5256)).

I think the standard Mac way would be to implement "Paste and Match  
Style" in the Edit menu rather than introduce a new preference.

It would be nice if the editor made this adjustment (mentioned by Rob  
Goedman) automatically.

Are you sure you don't want to just use something like Aquamacs or  
TextMate as an external editor?

Do you mean execute lines one at a time? You can hit command-return to  
execute only the line the cursor is on.

This would be very handy - this happens to me every once in a while  
and it is annoying. Of course it's my fault, but it's annoying  
nonetheless.
