[ESS] emacs theme for polymode with noweb files

[LaurentEss]

Hi Tyler,

  Thank you for the explanations. I well understood what you mean and I 
agree. But I did not success to apply  your approach. I disable 
hl-line-mode with the command with (global-hl-line-mode nil) but M-x 
describe-face doesn't work. Searching on the net, I found the commande 
C-u C-x =  and I was able to put the red color for << >>= which is a 
good beginning.  But the @ becomes red also, and I would like to put it 
in another color. I will investigate to understand how the face 
customization works. Thank you for the pointer.

Once you pick a theme that is reasonably close to what you want, if there are bits that you don't like, you can easily change them. Put the cursor over the offending characters, and call the function `M-x describe-face`. You'll be prompted for the face you want to see, and the default is the face of the character under point[1] (the cursor).

The next window that opens will show any styles that are applied to the face in question. You can change that to whatever you like, and apply it to the current session with `C-c C-c`. To save it permanently, type `C-c C-s`. Note that you don't see all the possible attributes by default, only the ones that have been changed. To see the other options, click the `show all attributes` button.
