Is there a good Vi(m) command for transposing arguments in a function call? Bonus points for Emacs

Question

For example if I have some code like:

foo = bar(\"abc\", \"def\", true, callback);

Is there a nice command to move true to the 1st or 2nd posit

Answer 1

I don't know the answer for vi, but in Emacs, transpose-sexps (C-M-t) will swap two arguments either side of the cursor. Actually transpose-words (M-t) was my first guess, but that leaves the quotes behind.
