(Author here) It's a ring buffer. I wrote it after evaluating the option to implement it in and into shell, as Anselm suggested, and found it too complex in regards to adding a vt layer and handling ncurses, as Alexander hinted as well. Also, preserving the history reliably while you change shells/users/machines makes it hard as well. And the option to start something like tmux first is just the same as implementing it in st, just in a very hackish way, as the result is the same. I still ponder to write an experimental shell where input and output is separated and where the last line is input and the rest is scrollable output. Scrolling through the input history would give you the corresponding output and all output would be preserved in variables to ease processing later on (think of piping old output through grep again and again without having to evaluate the command again). Anyone knows some code where this is implemented already? The idea is actually inspired from here: http://lists.suckless.org/dev/0911/2208.html and the option to use vi as a terminal: http://lists.suckless.org/dev/0911/2224.html Cheers Jochen
