Pick Tool and No Tool
Switch between configuration mode (pick tool) and operation mode (no tool). For further information on these modes, see the topic: Development Mode vs. Operation Mode.
The Pick Graphics button is one of the most frequently used buttons in the Configuration Toolbox. When selected, it activates the Pick Graphics tool and places the application in design mode, enabling you to configure and develop the application pages of your application.
Note: When an application is placed in design mode (i.e. the Pick Graphics button or any other button in the Configuration Toolbox except the No Tool button is selected), certain operational tasks (such as alarm acknowledgement) are disabled. To place the application in operation mode so that you can perform operational tasks, either close the Configuration Toolbox or select the No Tool button.
