emacs TAGS

[spitters]

M-. jumps to definition. Looking at the behavior of emacs TAGS, I would expect M-* to bring me back. Perhaps one could add such a key-binding?

I'm not familiar with M-*, though I do see a reference to it in the news for Emacs 20. When I use M-. to jump to a tags file, pressing M- complains about it being undefined. Do you know where `M-` is defined?

In any case, I think the standard command for this is now M-,, which does work with company-coq on emacs 25+. Can you try that and confirm that it works?

After M-. on "list", I get taken to Init/Datatypes.v

M-, gives "marker stack empty"

Here are the TAGS keybindings:

Thanks. Is updating to a newer Emacs an option?

I'm on Ubuntu 18.04:

emacs --version GNU Emacs 25.2.2

Hmm. Thanks. Let me check then.

Surprising. Here on Emacs 25.2, M-* says undefined and M-, jumps back. I tried in a C file with an appropriate tags file.

What does M-: (fboundp 'xref-push-marker-stack) return? What about M-: (require 'xref)? Does that raise an error? If not, does M-. followed by M-, work after this require?

What does M-: (fboundp 'xref-push-marker-stack) return? t

What about M-: (require 'xref)? xref

does M-. followed by M-, work after this require? Still the same error

Snap. Thanks for giving it a try.

Just to understand better, can you tell me what C-h k M-. returns in a C buffer, or some other language where you use tags? What about C-h k M-*? Finally, can you try M-x where-is RET xref-pop-marker-stack, too?
