If you right-click on the Project Explorer blank area ( if you want to remove a selection, press Ctrl+left click on the selected element), you are able to create the following BTT elements: flow, operation, view and BTT project.
The Operation… option launches the Transaction editor in the Operation page (Operation editor).
The Flow… option launches the Transaction editor in the Flow page (Flow editor).
The View… option launches the XUI editor.
The BTT Project option opens the XUI project create
wizard. The same options are available with no selection in the Project
Explorer if you go to the Menu Bar and select the File > New option
or you drop-down the list of options in the icon in the Tool Bar.
