It can be contrasted against orthopraxy, right-practice, where the actions are more important than the belief or intent.

Based on the other comments here, these orthodox file browsers are based on a sort of underlying language,

> The "orthodox" comes from a specific type of GUI, namely one that is driven by commands under the hood. UI elements are merely used to trigger commands that have the actual effect, and these commands could just as well be executed by hand, or automated into more complex commands.

It… kind of makes sense actually, if we stretch the definitions a bit, haha. The orthodox UI has some button, which is translated into a sequence of commands that represent the actual user intent.

The alternative is just to have the button do the thing directly, there’s no description of the user intent other than what the button does. It is quite a stretch but maybe we could call that the an Orthoprax UI.
