You use this option to access the display used to add, modify, and delete user-created property keys for devices or sensors. Once a custom property key is created, a new column appears, with the custom property key as the column heading, in the Device View, Custom Properties Editor view, and the View Device Sensors display.
You access the View Device Sensors display from the right-click option in the Device View and Map View.
This display allows you to manage custom property keys only. To identify the value associated with a custom property key, you use the Add Custom Property display in the right-click menu of the Device View, Map View, or Custom Properties Editor view. Until you identify a value for a property key, the fields in that property key column will be blank.
You can use the Configure Columns icon to show or hide custom property columns in either the Device View or the View Device Sensors display.
The Manage Custom Property Keys option in the Device menu, and the Manage Custom Property Keys icon in the Custom Properties Editor view, provide access to the Manage Custom Property Keys display.
