I’ve used these aliases since I first started using csh (below syntax for zsh):

  alias   .=cd
  alias   ,=pushd
  alias   ,,=popd
  alias   ,.='dirs -v'

No need to alias .. as in zsh you can use a dir name as a command to cd to it. Setting cdpath can further cut down on typing. For example

  cdpath=(. .. ~/go/src ~/src ~)
