> cpwd copies the current directory to the clipboard. Basically pwd | copy. I often use this when I’m in a directory and I want use that directory in another terminal tab; I copy it in one tab and cd to it in another. I use this once a day or so.
You can configure your shell to notify the terminal of directory changes, and then use your terminal’s “open new window” function (eg: ctrl+shift+n) to open a new window retaining the current directory.
