2 years ago Well, unfortunately the linux konsole just doesn't reveal this information about modifiers.
E.g., whatever modifiers you press with the ArrowDown key, you only get an Esc [ B sequence.
The only solution here would be to provide a patch for the linux kernel to send different sequences for modified keys in the konsole mode.
Btw., much of lanterna's input-decoding was contributed by me. I kind of know what I'm talking about ;-)

In the unemulated terminal, TERM=linux, the modifier ALT or SHIFT is not recognized. This prevent to use scrolling. I entered a few lines of logging and got the following output.
