I agree.  Changing the title and item group to a Feature Request.

Allowing to use the documentation browser with the "doc" command also from the CLI interface is a new feature in Octave 7. The corresponding docstring can still be viewed in the CLI with the "help" command.

Imho, adding an option for whether "doc" should open the GUI documentation browser or the info browser in the CLI shouldn't block Octave 7.3.0.

Changing release to "dev".

The code in question is located in scripts/help/doc.m at line 56

  ## Give event manager the first shot.

  status = ! __event_manager_show_documentation__ (function_name);

  if (status)

In Octave 5.2 this code was

  ## if GUI is running, let it display the function
  if (isguirunning ())
    status = ! __octave_link_show_doc__ (function_name);
  else

It seems like this should be configurable because some people running the CLI will want to stay entirely in a terminal environment, while others might still appreciate being able to open up a Qt-based document browser for help while still coding in the CLI.

It appears that the `doc` command (in `doc.m`) now tries to launch a GUI documentation browser always, versus only when the GUI is running.  This seems like it should be a configurable option.

I think a simple example to reference is

```octave
doc ls
```

In version 6.4, this launches a CLI Info browser when running with the `--no-gui` option.  In Octave version 7.X this launches a Qt-based Info browser.
