I'm using version 7.1.138 on Ubuntu 8.04, on this machine ciw - change inner word command does not work. No custom settings is done to vim. Does someone know why?
Debian/Ubuntu install vim-tiny by default. Installing the vim package gives you the full version. There's also vim-gnome (previously vim-full) which includes the full version as well as a GUI version. As far as I know (and there's nothing about this in the man page), vim behaves the same regardless of whether you invoke it as vi.
