I am relatively new to emacs and using emacs version 21.3.1 and trying out the ctags for emacs (mainly to jump to definitions).
I am working with a big solution with lots of projects. Problem is that whenever I am trying to jump to tags under a cursor using command M-. , it tries to find a tags table from current directory of the source file.
My TAGS file is located at the root of my solution. So I have to point to it using M-x visit-tags-table [path to my tag file].
Is there a way to set this when I start up emacs so I do not have to point to it every time?
