To delete material queries:
Select Delete Material Query from the toolbar or the Query sub-menu in the Groundwater menu.
Select the material queries you would like to delete. Note: you can select individual queries with the left mouse button, or multiple queries with a window, or all queries (in the view) by using Select All in the right-click menu.
When you are finished selecting, press Enter or right-click and select Delete Selected, and the queries you selected will be deleted.
A shortcut for deleting all material queries from a view is to select Delete Material Query, right-click anywhere in the view, and select Delete All from the popup menu. This will first display a dialog warning that you are about to delete all queries in the current view. Select OK to delete all of the queries, or select Cancel to abort the Delete All operation.
A shortcut for deleting a single query, is to right-click ON a query line, and select Delete Query from the popup menu. This will delete the query you selected.
