Prompt doesn't change with bindings to cd

[csswright]

• I've been trying out bindings to navigate the filesystem but they don't update the prompt to reflect the new $PWD (I actually thought the functions don't work to cd but they do). Any ideas how the prompt should reflect the updated $PWD?

• Unrelated, but I've been exploring ways to get to directories quicker. Wish e.g. hash -d b=~/bin and ~b to jump to that directory, the prompt becomes ~b. Is it possible for the prompt to be the regular path, i.e. ~/bin?
