These are probably nothing new to anyone on here but just in case
someone is nearly as ignorant as i am here goes.
do $<less /usr/info/dir> It gets a list of commands and an extremely
short description of what they do.

<up arrow> gets your previously typed shell commands.
I knew there had to be a way to do that but had not found the way until
someone showed me. Saves much typing.

Sorry for the boredom this must have caused.
