documentation/feature: 4.1 Point and click (MacOS)

[Stefan Vollmar]

Dear all,

when using the current Lilypond.app (2.13.35-1 and the stable one), 
Point-and-Click will work out-of-the-box for the Mac - nice. But there is no 
recipe on what to do if you prefer not to use the builtin text editor.

However, there is a solution for the Mac: distributed with lyqi by Nicolas 
Sceaux is EmacsPointAndClick.app - but this needs to be modified to work on 
Snow Leopard. Please find attached my correspondence with him. -

But I think there is a much better way: as Lilypond.app already handles the 
"textedit"-type URIs it should be possible for advanced users on the Mac to set 
LYEDITOR and, if set, Lilypond could then provide the functionality of the 
EmacsPointAndClick-AppleScript in a more general fashion, replacing the "do 
shell script" line with whatever is specified in LYEDITOR. 

Point-and-Click is a great feature of a great application. Thank you for 
Lilypond!

Warm regards,
 Stefan
