+The syntax for using the addprefix operator is as follows:
+ 
+     square brackets surround literal text value (e.g., addprefix[sometext] as shown in the example above)
+        
+     curly braces surround tiddler field references (e.g., addprefix{SomeTiddler!!somefield})
+       
+     angle brackets surround variable references (e.g., addprefix<somevariablename>)
