The property editor
This screen will show you all the available properties for a particular object type. If you have selected to edit an existing object then the fields will be filled in with the values that have been either stored previously or created by default.
Properties are split into three sections for most objects. These are, object details, simple properties and advanced properties. The simple properties will contain fields that you commonly use and all other fields will be classes as advanced fields. These are made available by clicking the appropriate tab at the tob of the dialog.
To modify a property, simply change the appropriate value. Changes will be made to the object when you click the 'OK' button. If you change the objects name, then you will be prompted to make sure you want to rename the object before the changes are committed. Clicking the 'Cancel' button will leave an object unchanged.
