The feedback/edit window is shown below:
Every time you add an item to the survey, question or not, it shows up in this window coded as: #:TYPE. The number is the number of the item in the survey page starting with 1. The type is the type of item, such as TEXT for a bit of text you have added or SHORT_TEXT for a short text question type. This window will scroll when filled and is active. You can select an item by clicking on that item. Double clicking allows you to edit that items values, e.g, the anchors in the Likert question. The divider has not settings that can be changed so it cannot be edited. However, whenever an item is selected it can be cut, copied, pasted, or deleted using the edit menu. Pasting goes in front of the selected item.
