AutoHotKey GUI with dependent ListBoxes

Create a minimal GUI with dependent ListBoxes that read the contents of two text files. 1. A Services ListBox that reads LongNames from [login to view URL] if List=1, sorted alphabetically. (A Service with an Alt is an unlisted alternative for the Alt.) 2. Selecting a Service displays a Keywords ListBox that reads Keywords from [login to view URL] if Service=[login to view URL] and Active=1, grouped by Group and sorted alphabetically. 3.1. Selecting a Keyword whose ID has no related Keywords displays an Actions ListBox. 3.2. Selecting a Keyword whose ID has related Keywords displays a Related ListBox that reads [login to view URL] if Service=[login to view URL], and Keyword, sorted alphabetically. Selecting a related Keyword displays the Actions ListBox. 4. The Actions ListBox lists the [login to view URL] and Keyword for the selected Keyword or related Keyword, then any Alt Service, sorted alphabetically. Selecting an Action sends [login to view URL] to a MsgBox, substituting * with the Keyword.
