How do I delete, cut/copy&paste and rearrange things in APT?
In the Hierarchical Editor (the tree like view on the left hand side) you can highlight an entry and then delete it using Edit>Delete from the menu above.If you would like to move an entry within the list, you can use the Cut and Paste options from the menu or you can drag and drop. You can select multiple entries by control clicking on several, or shift clicking at the top and bottom of a range of entries to be selected.Then you can use the cut and paste (or copy and paste) options under the Edit menu to move or copy the entries. (Drag and drop will not work for multiple entries.) For more information please see the video called Editing with the Tree Editor.
