Multiple Cursors in Vim

Use plugin vim-multiple-cursors.

Install this plugin with adding Plugin 'terryma/vim-multiple-cursors' into .vimrc.

The default key mappings is C-n for start multiple cursors and move to next, C-p for previous, C-x to skip, and for quit. For C-n conflicts with nerdtree, modify the nerdtree trigger to C-i:

nnoremap <C-i> :NERDTreeTabsToggle<CR>

Note:

Do not map 'next/previous' to C-j/k as follows:

" multiple cursors configs
let g:multi_cursor_next_key='<C-j>'
let g:multi_cursor_prev_key='<C-k>'

for C-j/k is mapped to keys jumping between windows.
