Thanks for trying to paraphrase what "discern textually" means to you, since
I have been having so much trouble with that phrase. Perhaps we means
something like "can be represented functionally in text"? Although it is the
granularity of the functionality that is often the problem. "Turn arbitrary
pixel black" seems functional, but isn't effectively functional.

Here is an example: double-clicking with the mouse often has different
behavior from a series of two single clicks.  The  difference between these
two gestures is based on the amount of time that elapses between the click
actions. If you can't click quickly enough, you may not be able to invoke
the double-click action.
