I don't think there's currently a standard way to detect shift-enter and
distinguish it from regular entire in a terminal.

The terminal interface gives applications sequences of individual bytes
rather than (in most cases) keypress events.  So for example, a terminal
application doesn't know whether "A" resulted from shift-a or from caps
lock being on when a was pressed.  Nor can it detect bare shift-key
presses.

There are some extensions to this interface with ioctl calls but a
challenge there is that they are potentially not portable between
operating systems, so you could get features that can only be
implemented on one OS and not others.

It seems like there are workarounds where terminal emulators can
generate escape sequences to distinguish these

so maybe one of those is popular or semi-standard enough that an
application like bash could consider treating it specially?
