Stefan, my setup involved using modus-vivendi to which I add a bold font
for everything.  But I want a special customisation for comments.  
Customisations
include having a normal weight, and having a keybinding that changes the 
contrast
ratio between the comment colour and the background.

My first thought has been to define a minor mode.  But from the comments from 
this
mailing list, I has been put forward to mo that what I am doing could be a very
non-standard customisation.  What would be the most appropriate way to customise
comments as described.  I would be grateful for examples on how I should 
approach
the task.
