'editwrd'/'ewrd'/'ew' does tab-completion relative to whatever $_WRD (working directory) is set to (e.g. by venv) and calls 'e' with that full path: https://github.com/westurner/dotfiles/blob/develop/scripts/_...
It's unfortunately not platform portable like vimer, though.
I frequently switch between Linux, Mac and Windows. Is there a good way to set up such aliases on Windows?
