With a few exceptions, tool layers are managed like any other group layer in ArcMap.
Create a tool layer
Executing the tool layer
Right-click the layer and click Open. Fill in the parameter values and click OK.
Viewing execution messages
Once the tool has been executed for the tool layer, you can view messages by right-clicking the tool layer and clicking View messages.
Saving a tool layer
Tool layers can be saved like any other layer. Right-click the layer and click Save to Layer File.
Renaming a tool layer
To rename a tool layer, click the layer and press the F2 key. Alternatively, right-click the tool layer, click Properties, then change its name on the General tab of the Group Layer Properties dialog box.
