Easy text exchange operator for Vim.

cx

On the first use, define the first {motion} to exchange. On the second use, define the second {motion} and perform the exchange.

cxc

Clear any {motion} pending for exchange.

To exchange two words, place your cursor on the first word and type cxiw. Then move to the second word and type cxiw again. Note: the {motion} used in the first and second use of cx don't have to be the same.

If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:

cd ~/.vim/bundle
git clone git://github.com/tommcdo/vim-exchange.git

Once help tags have been generated, you can view the manual with :help exchange.
