FXFileDict is to manage the icons.  To simply find the bindings string
of course you'd ask FXSettings (FXRegistry) directly.

Its a ';' separated string which whoulc be fairly easy to parse with sscanf.

Try 

	sscanf(buffer,"%[^;]%[^;] ... ",command,type,....);


This is little known (I didn't know it either until recently) but sscanf() can be
told to scan characters adhering to certain character class, so its easy to split 
stuff up based on a certain delimiter.

My own code could probably be simplified to use this as well...
