Hello! Konsole is super cool terminal!

For example we have terminal window with 1000 lines and 80 columns.
Can we get the last 100 lines? This will be the matrix 100x80.

Maybe there is workaround how to achieve this?
If it's easy breeze please give a piece of code or point to docs.
If you know how to do it may be not in Konsole and in another terminal tool please tell because it will be very helpful.

Thanks!
