Tag navigation in vim

Just adding this answer because I don't have the rep to edit or comment on the accepted answer, but <C-t> actually corresponds to the :pop command, not the :tag command as was stated.

:pop is for moving "backwards" in the tag stack (will result in 'at bottom of tag stack' message) and is the command with the default keybinding <C-t>

:tag is for moving "forwards" in the tag stack (will result in 'at top of tag stack' message).

I am not aware of any keybinding for :tag like for moving backwards, so I have mapped (not ) to tag.

nnoremap <C-[> :tag<CR>

You can also use Ctrl+I and Ctrl+O to move forwards and backwards respectively through the jump list. This works with tag commands since they count as jump movements.

So to:

• Jump to a tag: Ctrl+].
• Jump back: Ctrl+O.
• Jump to a tag again: Ctrl+I.

The tag stack is created by all your "jump to definition". Each time you do <C-]>, the tag you jump to is added to the tag stack and you are able to use <C-t> or :pop to jump back to the previous tag in the tag stack or :tag to go the other way. Both :tag and :pop take an optional count so :5pop would go to the fifth previous tag.

See :help tagstack.
