Windows subsystem for Linux Bash - How to page up and down?
If there's a way to do it in the standard Windows console, I haven't found it. I've switched to ConEmu, and Ctrl-PgUp and Ctrl-PgDn work. Ctrl-UpArrow and Ctrl-DownArrow work too.
ConEmu has numerous other benefits; color themes and better cut-and-paste to name a couple of my favorites. You can run WSL bash, cmd, PowerShell, Cygwin, and more in ConEmu.
