Switch to original buffer after chasing tags in Emacs

Question

Answer 1

I believe that M-. calls find-tag by default. You should be able to go back up the stack of locations with M-* (pop-tag-mark).

From C-h f find-tag:

A marker representing the point when this command is invoked is pushed onto a ring and may be popped back to with M-*. Contrast this with the ring of marks gone to by the command.
