Poor man’s multi cursor in VIM

I tried vim-multiple-cursors but it was just doing weird things and not replacing the right words, so after digging around for a while I came up with this:

Simply add it to ~/.vimrc.

function! PoorMultiCursor()
	let word = expand('<cword>')
	if strlen(word) > 0
		call inputsave()
		let repl = input('replace "'.word.'" with: ')
		call inputrestore()
		if strlen(repl) > 0
			execute '%s/\<'.word.'\>/'.repl.'/g'
		endif
	endif
endfunction

" sublime text's ctrl+d / ctrl+alt+d (find all)
inoremap <C-d> <C-o>:call PoorMultiCursor()<cr>
nnoremap <C-d> :call PoorMultiCursor()<cr>

function! PoorMultiCursor()

let word = expand('<cword>')

if strlen(word) > 0

call inputsave()

let repl = input('replace "'.word.'" with: ')

call inputrestore()

if strlen(repl) > 0

execute '%s/\<'.word.'\>/'.repl.'/g'

endif

endfunction

" sublime text's ctrl+d / ctrl+alt+d (find all)

inoremap <C-d> <C-o>:call PoorMultiCursor()<cr>

nnoremap <C-d> :call PoorMultiCursor()<cr>

Basically it's the same as using alt+f3 in Sublime Text.
