You can't. <C-]>
jumps you to the first occurrence of the word under the cursor in your tags
file.
Vim itself has no mechanism to guess what method you want to jump to or infer scope from context and not much information can be gleaned from your tags
file to make that feature smarter anyway.
You can use g<C-]>
(same behavior as :ts
) or g]
(same behavior as :tj
) as alternatives to <C-]>
.
