Here's a small code sequence you can put into your ~/.emacs. It
assigns a color to the TAB-Key and to a trailing space character at
the end of the line. I think I found it in this news group some years
ago. Works for me quite well and fast.
(custom-set-faces
'(my-tab-face ((((class color)) (:background "lemon chiffon"))) t)
'(my-trailing-space-face ((((class color)) (:background "Gold"))) t))
(add-hook 'font-lock-mode-hook
(function
(lambda ()
(setq font-lock-keywords
(append font-lock-keywords
'(("\t+" (0 'my-tab-face t))
("[ \t]+$" (0 'my-trailing-space-face t))))))))
