Display history commands.
Use the partial online help. That is, when you input an
incomplete keyword and press <Tab>, if the input
parameter uniquely identifies a complete keyword, the
system substitutes the complete keyword for the input
parameter; if more than one keywords match the input
parameter, you can display them one by one (in
complete form) by pressing <Tab> repeatedly; if no
keyword matches the input parameter, the system
displays your original input on a new line without any
change.
