In conjunction with https://stackoverflow.com/questions/3131393/remapping-help-in-vim-to-open-in-a-new-tab , I'm looking to also make the shift-K shortcut that opens help in a new tab.
I first tried
nmap <S-K> :tab help expand("<cword>")<CR>, but it doesn't actually work - the
expand is apparently taken literally as the help tag text, and is not executed.
So, how do I remap
<S-K> to get help on the current word in a new tab in Vim?
