I'm a newbie to Geany, and only a little experienced with Scintilla, but 
I'll try to answer your question anyway.  (I am one of "all" ;-)

There are at least two answers (and I assume we're talking about C++ 
code).

You can revise or write a new lexer for Scintilla that handles those 
marks, or you can use the alternatives already defined in the C/C++ 
lexer for Scintilla, which are:

For opening:

//{

and, for closing:

//}

These don't work out of the box in Scintilla, you must set a specific 
property to make them work--let me see if I can find that...ahh, 
yes--you need to set the property "fold.comment=1" in a property file.  

In Scite, I set it in my user property file: ~/.SciTEUSER.properties--I 
assume that Geany makes use of similar property files, somewhere, 
somehow.  

There is a similar property available named fold.preprocessor=1 that is 
supposed to fold preprocessor stuff like #if #endif blocks--so far that 
hasn't worked for me, but I haven't tried very hard. ;-)

I'm almost sure these work only for C/C++ languages, specifically those 
lexed by the LexCPP.cxx lexer.

Hope this helps!
