How to use ctag with GNU Emacs

HOW TO USE WITH GNU EMACS

Emacs will, by default, expect a tag file by the name "TAGS" in the current directory. Once the tag file is built, the following commands exercise the tag indexing feature:

M-x visit−tags−table FILE

Select the tag file, "FILE", to use.

M-. [TAG]

Find the first definition of TAG. The default tag is the identifier under the cursor.

	M-*		Pop back to where you previously invoked "M-.".
	C-u M-.		Find the next definition for the last tag.

For more commands, see theTagstopic in the Emacs info document.
