This guide uses little 'ascii-icons' to distinguish if a button is linked
 to a text, sound, picture or other. This is useful for example if you press
 a button which plays a soundfile, but nothing happens, because your speakers
 are not connected.

 I use the following symbols so far:


 	 ->	link to a text node

	[º]	link to a picture or brush

	«·»	link to a sample

	 *	link to a program
