This isn't a setting but is a convenient way for you to display the active status of your emulation connection.
You may be asked to click on the "Click here to report a Problem" which will provide you the ability to write the description of a problem you are having with the terminal emulator--it will also capture the active WebSocket Internal Log to help in diagnosing your problem.
This button will clear any custom keyboard settings you have made and will reload the set of customized keys created by your administrator.
