Hi,
I am a newbie struggling to get started.  I can see a lot of potential in using Geany to process my ".abc" music files so I am sure once I get going it will be very useful.
I am finding the documentation a little frustrating, I spend all my time following links to different parts of the documentation file without ever finding any good examples.  What I need right now is a good tutorial on how to get syntax highlighting working on my new filedef.

Here is an example ".abc" file:

As can be seen it has a very simple structure. Syntax highlighting would consist of highlighting comment lines (beginning with a single %) - colour A say, start-of-tune lines (X: lines) - colour B, Title (T: lines) - colour C, directive lines (beginning %%) - colour D.  Then key words highlighted (M: K: etc)  That is about it really, except I would really like to see all my T:'s in the symbols tab so that I can quickly go to those tunes (I guess that is a separate issue of tags that I have not yet delved into)

Here is what I have done so far to make a start:
1) Created an entry in my filetype_extensions file to add:
[Extensions]
ABC=*.abc;

2) Created a filetypes.ABC.conf file as follows (removing preset comment lines)
[styling]
comment=#c00;;;true

[keywords]
primary=X: T: M: K: C: L: Q: K: V: P:
secondary=N S B %%chords endchords staves

[settings]
extension=abc
lexer_filetype=ABC
comment_single=%
comment_use_indent=false
mime_type=text/vnd.abc

This has no effect as it stands, though it is clearly being read because if I change BOTH [styling] to [styling=C] and "lexer_filetype=ABC" "lexer_filetype=C" then I get some highlighting, though obviously not what I am looking for.  It is, however, interesting to note that it then highlights "N", "B", "endchords" but NOT "%%chords" or "X:", "T:" etc - which makes me think that ":" and "%" may need special treatment - escaping in some way.

Clearly I am missing something that I am not doing correctly to get the syntax highlighting to work.
Then there is the question of where to go for the symbols.

A noddy guide to getting started, with examples would be very useful. Thanks in advance.
