Re: Scientific notation quick toggle?

2008-09-18 by Rob

Hey Michael,

Thanks for such a great post.  Looks like it is time for me to learn how 
to make working directories.  :)

Do you have any more chemistry related schemes?  I'm the only one
that I know of at my school with an HP in a sea of Ti's so I don't get
to swap tricks - but I do get to show off.  :P
