You can copy text in any editor, you know.
I am fully aware of that, I'm just curious what the specific key combination Ctrl+V does given their unusual (to me) interfaces :)
I don't think ctrl-v does anything in Emacs. Not completely sure about vi, but I think nothing happens there either. (By default, that is)
In vim it's visual block mode, which allows you to highlight a rectangle of characters. Original vi does not have that
In vim it invokes vertical visual selection (visual block mode)
Oh, right, it selects a rectangle, is that it?
I never really used that, it's not a very common command. Maybe for tabulated data, but that's not something I'd edit with vi... (or vim, nowadays)
Yes sort of I think. I use it often when I want to edit multiple lines at the same time e.g. adding the same prefix at the beginning of every line or in the same cursor position on every line.
