cd with no argument is the same as 'cd ~' in all shells I've used. Been that way for 20+ yrs. Save 2 characters, use 'cd<enter>'
A little coverage of cdpath would be nice too. It is very helpful as a character saving technique.
cd .. takes you to home directory. Many of these were the same in DOS 3.3 and up.
Just to add some basic use to the good examples before:
cd / - Switch to root directory
cd .. - Switch to one step prevous directory in the tree
cd some* - Switch to directory that starts with "some" and anything else afterwards
