• Replace contents in multiple files in Dired mode using query-replace-regexp, which is bound to Q.
  • Replace multiple files names in Dired mode using % R.

  • Copy multiple files to new files with the names generated by regular expression replacement in Dired mode using % C. N.B. This only works for regular files, not directories. For directories, I have to use Bash command:

    find . -maxdepth 1 -name "hmatrix-Tvmult*" -print | while read f; do cp -r "$f" "${f//Tvmult/Hvmult}"; done
  • Open link directly from Konsole using emacsclient by editing the text editor command as emacsclient +LINE:COLUMN PATH (in Konsole profile: Mouse → Miscellaneous → Text Editor Command).
