[crtl]+[e] is used in emacs mode (default) on the shell to jump to the end + of the line. But, its also used so signal a scroll down mouse event from + terminal emulators to the shell an other programs. + + * A workaround is to use vi mode in the shell. + * Or to give up mouse support (default behavior) + +2. scroll could not handle backward cursor jumps and editing of old lines + properly. We just handle current line editing and switching between + alternative screens (curses mode). For a proper end user experience we + would need to write complete new a terminal emulator like screen or tmux. + +What is the performance impact of scroll? +----------------------------------------- + + indirect OpenBSD +- - - + 0x 7.53 s + 1x 10.10 s + 2x 12.00 s + 3x 13.73 s + +Development +----------- +You can [browse](//git.suckless.org/scroll) its source code repository or get a +copy using the following command: + + git clone https://git.suckless.org/scroll + +Download +-------- +* [scroll-0.1](//dl.suckless.org/tools/scroll-0.1.tar.gz) (2021-01-19)
