you can put the following lines in a script file in your plugins directory:

    highlight default link CurrentWord IncSearch

    function! s:HighlightCurrentWord(on)
        if a:on
            augroup HighlightCurrentWord
                au CursorMoved,CursorMovedI * exe 'match CurrentWord /\<' . 
escape(expand('<cword>'), '\/.*$^~[]') . '\>/'
            augroup END
        else
            augroup HighlightCurrentWord
                au!
                match NONE
            augroup END
        endif
    endfunction

    command! -bang HiCurWord call s:HighlightCurrentWord(expand('<bang>') != 
'!')

Then, if you execute ":HiCurWord", all occurences of the word under the
cursor will get highlighted. If you move the cursor to a different word,
the new word will get highlighted.

":HiCurWord!" switches highlighting off.

If you want to save some key strokes, define mappings like

    nnoremap <F12> :HiCurWord<cr>
    nnoremap <S-F12> :HiCurWord!<cr>

Regards,
Jürgen
