Looking up word under the cursor in Vim in OS X default dictionary

When you have two displays and one of them serve as a distractless environment for writing, make use of the second for a quick look up of word under the cursor. MacDict comes to help you. First install it:

Plug 'jonhiggs/MacDict.vim'

Then use this binding so that it is easily available at your fingertips (I switched from <kbd>\\</kbd> to <kbd>,</kbd> as the leader key).

map <leader>d "dyiw:call MacDict(@d)<CR>
