Answer by barlop for How can I make Vim paste from (and copy to) the system's clipboard?

Following on from Conner's answer, which was great, but C-R C-p + and C-R C-p * in insert mode is a bit inconvenient. Ditto "*p and "+p from command mode.

a VIM guru suggested the following to map C-v to what C-r C-p + does.

You could have :inoremap <C-v> <C-o>"+p for insert mode only

if you really wanted to override blockwise visual mode (not recommended by him as visual mode is good) you could have map <C-v> "+p
