1 is the index of the subexpression that should be affected,
see this screenshot. So you search for the whole expression,
but colorize only the subexpression pointed to by the index.

See how the code corresponds to the first two lines?

If you don't have any subexpression, just a single expression
that might be as plain as a word, you don't need an index,
instead use (word . face) - I think I mentioned
this...? Nevermind.

Anyway here is an example of that:

Look at the code and think. What does the file name refer to?
