Find out to which highlight-group a particular keyword/symbol belongs in vim

Question

I am coming to Vim from TextMate, and I would like to customise my vim colorscheme. It would be really helpful if I could find out to which highlight-group(s) any particular

Answer 1

Another way to get lots of information about the highlighting:

map  :echo "hi<" . synIDattr(synID(line("."),col("."),1),"name") . '> trans<' . synIDattr(synID(line("."),col("."),0),"name") . "> lo<" . synIDattr(synIDtrans(synID(line("."),col("."),1)),"name") . ">" . " FG:" . synIDattr(synIDtrans(synID(line("."),col("."),1)),"fg#")

If I move over a comment in a C file and press F3, I get:

hi trans lo FG:#00ff00

which shows that it is in the highlight group cCommentStart, which is linked to Comment and coloured in green (#00ff00). This is (modified) from here, see that page for more information.
