Editing a dataset
Edit mode must be activated for a dataset in order to edit it. (This can be done using the icon in the tool bar, the keyboard shortcut Ctrl+E or the context menu entry “Edit on/off” on the dataset.)
A renewed click on the icon switches edit mode back off again and any changes made in the meantime are saved. If more extensive changes are being made, they can be stored before they are finished by clicking the icon or pressing Ctrl+S.
Several datasets can be in edit mode simultaneously. To this end every dataset must be opened on a separate workspace tab.
