I'm sure this has been asked a number of times before. What is the easiest
thing that can be done so that when we click "edit" we see the Mediawiki
code highlighted in different colors and various other settings instead of
it being plain text?
This is not highlighting for a computer language. Its highlighting for the
default mediawiki code. For example: [[Hello|My link]]
Just an example: 'Hello' can be in red, and the other part can be in green
and brackets are bold and so on.
Is there an extension that can be installed?
This one, is for computer languages, so its not what I'm looking for:
