Tip for trouble shooting the VIM syntax highlight

It is easy to do a VIM syntax highlight file, while it is a little difficult for you to do the trouble shooting, especially when you do a recursive pattern match with `contains`, `nextgroup` keywords.

Here is a small tip can help you a little bit.

put this into your ".vimrc" file

" display the syntax name under the cursor
map <F12> :echo synIDattr(synIDtrans(synID(line("."), col("."), 1)), "name")

For the next time, when you met some syntax highlight error, you can key in <F12> at the error place, VIM will tell you "what kind syntax ID that it is thing under the given position".

Keep fun! :)
