" <Leader>h toggles the under-cursor highlighting
:map <Leader>h let g:under_cursor_hl = 1 - get(g:, 'under_cursor_hl', 1)

" Use it in the CursorMoved autocmd
:autocmd CursorMoved * if get(g:, 'under_cursor_hl', 1) | exe printf('match IncSearch /\V\<%s\>/', escape(expand('<cword>'), '/\')) | end

Or am I missing something?
