Hi, when in a shell you can use "shift+PageUp" to scroll up the page
and "shift+PageDown" to scroll down,
or "enter" to get back to the prompt.
The amount you can scroll will depend on the amount of memory available to the shell/terminal.
A nice little cheat sheet from fosswire....
see how you go, cheers, Glenn
ps, the standard commands may not be enough to do what you want,
[glenn@GamesBox ~]$ man ls
[glenn@GamesBox ~]$ info ls
[glenn@GamesBox ~]$ ls --help
But as mentioned above by "keratos", the pipe function adds some control to the lookup.
ls | more
ls | less
hit q to quit/exit
