Properties
Basically, you have two ways in which to change the properties of graphomate tiles:
Using the Standard Properties Sheet, that shows all the parameters in a structured list or via the Additional Properties Sheet. The latter offers a more user-friendly Interface.
The check boxes 
in front of properties in the Additional Properties Sheet are used to control the visibility of elements and activation of functions. The data source to be used can only be assigned via Drag&Drop to the component or to the Standard Properties Sheet under Data Binding.
By pressing the F5 key, both the range of characters as well as the Additional Properties Sheet can be reinitialized. This is sometimes necessary when changes in the properties are not adopted directly in the character range.
