[Aptitude-devel] Bug#748427: menu during package config defeats this user

[Lou Poppler]

Package: aptitude
Version: 0.6.8.2

I used interactive aptitude to install several choices from within task
debian-science.
Near the end of the install process I got a screen with a text menu which
claimed to be "Configuring science-config"
and instructing me: "Please select, among the whole system user list, users
who should get a Debian Science user menu."
with a text-mode list of users with apparently text-mode check boxes by
each username, and choices <OK> and <cancel>
at the bottom of the screen.

Unfortunately there was no hint about what keys or what input might affect
the check boxes or might navigate to the OK and Cancel
buttons.  I wanted to select both users, and the cursor seemed to be inside
the first check-box, so I guessed that maybe the enter
key might select that check box.  This was a bad choice, because it exited
me from the menu, apparently without selecting any user.

After looking at man files, and help documentation, I still have no idea
what I should have done.
I also have no idea how to revisit this choice and select some usernames.

I file this bug, because I think it would be nice to have some hint on the
text-mode menu screen,
like maybe "[X selects/unselects]"  "[TAB moves to next option]"  ["ENTER
means exit"]
or _whatever_ the actual inputs are that I should use with this menu screen.
Or even some text explaining where to look to find out how it works.

If this text-mode screen comes from some other program invoked by aptitude,
I would appreciate even learning that information.
