In fact you could condense all of these into "know your tools extremely well", and you can take it further to "optimize yourself/your environment relentlessly".
I've known great hackers who used Eclipse, sam, acme, Brief, UltraEdit and everything under the sun.
Working with someone who doesn't know their chosen tools (people who use menus to work their editor, hand edit things instead of using sed/awk/perl, etc) is extremely painful, and seeing someone profess to use a tool but not operate it well is a huge warning sign to me. Same with slow typists: pair programming with such sucks.
