Hi; In the Emacs tutorial I am using I have come to the TAGS file compilation part. Following the instructions in the Tutorial and the Info Manual as well as digesting the process has not been too difficult. Neither 'locate' or M-x find-tags shows an existing TAGS file for emacs or elisp. What I want to check is where to create the TAGS file for both of these. I know I would want to put a TAGS file in a directory were I am building a project in the future but.. where should I put the TAGS file for Emacs itself. The Tutorial and Manual only ambiguously say: "in the appropriate directory" then give me suggestions for directories I and emacs don't use. Plus they make reference to source files which don't seem to exist separately on my installed version of emacs. (I can download them if need be.) I do have '/usr/share/emacs/21.4/lisp/emacs-lisp/' and '/usr/share/emacs/21.4/lisp/' that contain *.el (text) files. Would it be normal practice to compile TAGS files in those two directories? Do I want to use each TAGS file with M-. separately or should I combine them? However that is done? -- Regards Bill
