Did you know you can access the properties of a control test template from anywhere you see a control test template link?
If you double click on any control test template link (or right click on the link and select "Properties"), it will display the properties of the source control test template. If you have the appropriate permissions, you can also modify the control test template. Saving these modifications (by clicking "OK") will automatically update all items that the particular control test template is linked to.
In addition, if you are managing the control test template links through the "Templates" tab of the object's "Properties" window, you can access the properties of the control test template by simply double clicking on the control test template in either the "Templates Assigned" or "Templates Available" area.
For example, if you were to double click on "Drilling Operations" control test template in the variable setup window above, it would open up the properties of that control test template (shown below).
