All Entities within the Broker have the ability to have context variables associated with them. Most add and edit dialogues have the ability to make context variable assignments. To add/change/remove a context variable, click the Context Variable panel to expand it.

Editting Context Variables

You will see any context variables already associated with the object, called local context variables in bold, and any inherited from above in normal face. Since context variables can be defined in terms of other context variables, the display has two value columns: actual and effective. Actual shows the value truely associated with the variable, where as effective shows the resulting value, after variable expansion has taken place. The + button allows new variables to be added. The - button removes existing ones. You change an existing local variables defintion by clicking on the actual value. You can also provide a local definition for an inherited value by clicking on the actual value and typing its new value.
