How to highlight percentage sign "%" for fortran code in emacs?

Question

How can I highlight in Emacs the percentage sign "%" for accessing members of a type?

Answer 1

Add the following to your .emacs:

(font-lock-add-keywords 'f90-mode
        '(("%" . font-lock-keyword-face)))

This highlights % in the same colour as keywords like if, then, call, etc. There are a load of predefined faces listed in the manual, or you can specify a face manually.
