Answer 1

I don't think this is possible.
may be you can do is
during the enter key is pressed
    call method cl_gui_cfw=>set_new_ok_code
             exporting
                 new_code = 'DUMMY'.
and in the user command
if ok_code eq 'DUMMY'
    call method g_grid->check_changed_data
      importing
        e_valid = v_valid.
    if v_valid ne c_x.
      call function 'POPUP_TO_CONFIRM'
        exporting
          titlebar              = text-025
          text_question         = text-026
          text_button_1         = text-027
          text_button_2         = text-028
          display_cancel_button = ' '
        importing
          answer                = v_answer.
endif.
