There are all sorts of ways to do things in your shell environment without
reaching for the arrow keys. For instance, if you want to move up to the
previous command, you can hit Ctrl-p. To move down to the next
command in your shell history, you can hit Ctrl-n.
But what if you want to move to the beginning and end of your entire shell history?
Find your meta key (probably the one labeled alt) and hit META-< and
META-> to move to the end and beginning of your shell history,
respectively.
