    This check is redundant because I know the data is in a sorted order.

The feature is called 'Scroll Marks' and in a nutshell it allows you to mark line numbers in Konsole's output and then using next and previous menu options, quickly scroll to those points.

This means that you can put 'echo -en \\06' in your PS1 prompt and Ctrl+Up and Ctrl+Down immediately scroll you up and down between all the commands you've executed. So when that cat or grep statement suprises you with a massive amount of output, it's just a key combination away to go up past it again. And no fear of manually scrolling too far in each direction.

If you're a dev you can put it in your warn statements so when tailing logs it's easier to navigate to where you want to. If you work with grep/cat a lot, a simple sed command can make finding stuff much quicker and simpler.
