Use Space (SPACEBAR) to page, Enter (enter) scroll down one line, or use j , k (Vim Editor's move key) to scroll backward one line forward. Press the h key to show use Help (because man uses less as a reader, which is less the tool's Help), press q exit

For more detailed help, you can also use info commands, but man it is often enough to use them. If you know the purpose of a command, just want to quickly look at some of its specific parameters, then you can use --help parameters, most of the commands will have this parameter

e.g. LS--help
