Well, I have to admit to never really understanding the shortcuts that I have seen people use. ;-) I guess I'm brain damaged, but I have to do it in binary. As far as tools are concerned, I totally agree with the person who pointed out that in design meetings, you often don't have any tool handy except your head. Sure, you may have an IP subnet calculator on your Palm, but the client is going to look at you askance as you bury your head in the itty-bitty screen, trying to use that silly stylus thing or Graffiti, giving them no eye contact the whole time you're puttering with the tool. Use your head and look professional and like you're worth the big bucks that they are paying you.
