As background: I am a beginner in VIM and I want to go through the built-in vim manual, but with my own copy (not the system copy) so that I can practice in the manual text as I go along (I also bought the book Practical VIM and went through vimtutor).
To do this I went to the location where these manuals are located:
/usr/local/cellar/macvim/8.1-161/MacVim.app/Contents/Resources/vim/runtime/doc
and copied the contents to a directory in my documents directory:
sudo cp * ~/Documents/vim_learning/vim_doc
Now, I want to navigate this documentation using ctl-] and ctl-o but I can't in the versions I copied, and also when I just open a copy in the main doc folder using vim. I get E426 tag not found: foo error. Of course can navigate like I want to when I use the :help user-manual command. To get around this I presumed that I had to tell vim to use the tags file tried adding set tags=./tags; to my vimrc, which I verified was working by adding and removing lines to change the color scheme. This did not work. Is there any quick way to make these navigation tags work?
I am running this vim version:
