Descriptions can be added to the objects by right clicking over each object, selecting the Properties option, and filling the Description box.

To use the procedure, you may type the procedure name in the VBA Immediate window, like AllDescriptions, and then press Enter.

Code (some lines may wrap):

Public Sub AllDescriptions()
' This procedure finds the names and descriptions (from the property
' sheet) for all the types of objects in the database.  It creates results
' in the Immediate window, like "Form+frmOrdersEdit:Add/edit Orders data",
' where the object type = Form, object name = frmOrdersEdit, and the object
' description = Add/edit Orders data.

' You can copy the results to column A in an Excel workbook that has the
' following formulas to parse the list:
' Object Type =LEFT(A1,SEARCH("+",A1)-1)
' Object Name =RIGHT(LEFT(A1,SEARCH(":",A1)-1),LEN(LEFT(A1,SEARCH(":",A1)-1))-SEARCH("+",A1))
' Object Desc =RIGHT(A1,LEN(A1)-SEARCH(":",A1))
