Keywords are:  'history commands'

 Syntax:
 history
 !!
 !<number>
 !<command>

The history command will show you a listing of the last 15 or so commands you
have used.  Each command is associated with a number.  One command may have a
highlighted red number - this command will be the next one to be replaced if
you type a new command in.

The ! or !! commands will repeat the last command you used.
The !<number> command will invoke that command number listed with the history
command.  For example, '!13' will invoke command number 13 from the command
listing.
The !<command> command will invoke the first matching command in the history
list.  Only the first word is checked.  For example, '!say' might invoke the
command 'say hello' from your command history.
