Repeat last command with an exclamation? Vim

Question

When I've just typed a huge command such as:

:e ~/Projects/foo/app/views/bar.rhtml

Vim inevitably tells me that I haven't saved the current buffer. Is there a quick way to repeat the command with an exclamation point, without having to retype the whole thing?

Answer 1

:e! #

When specifying vim files, % is a shortcut to the current file and # is a shortcut to the "previous" (really, more like "other") file, which in your case is ~/.../bar.rhtml

Answer 2

q: will bring up the history and you can edit the commands directly and then hit enter to run them again, or you can do as zigdon suggested and :<up><home><right>!
