How to implement a custom tag in VIM using CTRL-]?

Question

If: VIM uses h, it will automatically follow the links | via CTRL + ] , opening new help topics and maintaining a list of tags ( CTRL + T will return to the navigation history). How to implement this behavior in my own format? For example, I want CTRL + ] in the text inside {} to open a file called something.txt and CTRL + T to return. How to implement this?

All this is done using tags. In essence, vim files are simple text files, but they are supported by a file in the same directory as "tags". This entire file contains entries that look like this:

'bg' options.txt /*'bg'* 'bh' options.txt /*'bh'* 'bin' options.txt /*'bin'* 'binary' options.txt /*'binary'* 'biosk' options.txt /*'biosk'* 'bioskey' options.txt /*'bioskey'* 

Each line is a tag entry, divided into three fields: the tag identifier, the file in which the tag is located, and the ex command to find this tag: any ex command works; as you can see from the above example, vim help files just use the search command: '/'.

You can either write the tag file manually, or use a program such as Exuberent ctags to automatically create the file. A tag file is usually read from the same directory as the file you are editing, but you can change it in Vim by setting the tag parameter.
