In VIM how can I configure ctrl-v to enter visual blockmode while in insert mode?

Question

My Google skills failed me. I thought this would be an old, well worn question.

In VIM input mode, how do I get <c-v> to be recognized as if I were in Normal mode, i.e. enter visual blockwise mode?

I tried a noremap! <C-v <ESC>:visual block, but that obviously isn't quite the right set of magic words.

NOTE: changed "edit mode" to "insert mode" as suggested by @Explosion's comment.

What you want is inoremap, which maps in insert mode. You can just use <C-v> since it is not remapped.

inoremap <C-v> <Esc><C-v>
