Extend Delphi 10.3 Code Editor

[dkjMusic 0]

I want to extend the editor, perhaps using the Open Tools API, to open a fly-out menu automatically when a word(s) is highlighted in the editor. The Opera browser does this as shown in the screenshot below. I posed this topic on the IDERA Community forum and have received no replies. Cut and Paste could be added to the fly-out context menu. Can anyone point me to an example or how to get started?

You can start from examining available OTA interfaces for necessary events and methods. Anyway the code editor is just a Windows' window (heh) so it probably supports standard WM_*/EM_* messages
