Dear Mr. Kremer, first of all I like to thank you for all your work you have done on dired-mode! I have a problem when using %R (dired-do-rename-regexp). I like to use a kind of computed replacement string (with a Lisp expression), like it is possible with the normal replace-regexp command. This seems to be not possible, or do I make an error in masking the replacement string? E.g.: when I specify the strings Rename from (regexp): \([0-9][0-0]\) \(.+\) Rename \([0-9][0-0]\) \(.+\) to: \,(+ \#1 3) \2 I get the message "Invalid use of '\' in replacement text" I'd appreciate your help. Is this my fault or are there plans to implement this into dired mode? I know that there is a workaround with wdired, but really would like to see it in dired itself. Kind regards, Ado Arnolds
