Somewhat along the same lines, as I regularly SSH to other hosts with the same network filesystem mounts, 'scd' starts an SSH session on a remote host in the same directory.

  #!/bin/bash
  # SSH to remote system and change into same (current) directory
  DIR=$(pwd)
  ssh -t $1 "cd $DIR; bash -l -i"

For fish shell users, you get chronological directory traversal with Alt-Left Arrow and Alt-Right Arrow.

This is a neat and useful trick, and I will be borrowing it. Thanks!

Abbreviate moving up in the directory hierarchy:

  alias ..="cd .."
  alias ...="cd ../.."
  alias ....="cd ../../.."

Just keep typing period and hitting enter until you get where you want according to your prompt. I haven't found much use for more than four periods. One period would be well-defined but useless.
