How do I map a key combination to perform a command in Vim?

I want the key combination <C-X> to run the command :! python application.py. From all my understanding of mapping, I tried the following: :map <C-X> :! python application.py which almost works. It just opens the command line and types the command in, but I still have to press return for the command to launch.

Is there any way I can get it to run the command as well?

Don't forget you can escape any key sequence with CtrlV (in Insert mode). So another way of getting the keycode for "Return" is CtrlVEnter. It will come out looking like ^M.

I found an answer in an unrelated post while doing my last searches before posting the question. It seems that putting <CR> behind the command executes it, making this do what I wanted:

:map <C-X> :! python application.py<CR>

According to the comments (thanks to melpomene) <CR> means "carriage return", which in effect means "press enter" and is just what I needed in this case.

Slightly related, I also found out that :!! repeats the last shell command executed, making my map somewhat superfluous.
