Some shortcuts for console work

[btiffin]

.: %.
..: %..

Now

>> change-dir .. 

will take you up a level, never hitting the shift key
And of course, change-dir is far too much typing so

cd: :change-dir
pwd: :what-dir
ls: :list-dir

goes in user.r as well.

N.B.  Be careful getting used to a shortcut like that (if it is stashed in user.r) and then letting it slip into a script. No fair shipping  open ../data/filename  to a customer that doesn't have the definition.
