Description

I'm interested in extending the behavior of text completion.

I'd like to make a (user defined) function call when a text-completion is selected from the dropdown list (e.g., partial match populates a drop-down, I use the arrows to find desired item, and press enter to select it; this action executes a user defined action). Where could I modify the source code to achieve this?

Research direction

The issue does not name a file, test, or entry point. Start by tracing the completion dropdown flow from partial-match display through arrow navigation and Enter selection. Done would mean a documented user-defined function is invoked when a completion is selected, with coverage for that interaction.
