How do I jump to a tag in Vim and automatically choose if there is only one match?
:tjump {name}
Vim's :tjump is the smarter sibling of :tag and :tselect.
Tag: ctags
How do I navigate through code using tags and the tag stack?
<C-]> / <C-t>
The command jumps to the definition of the keyword under the cursor using a tags file, and jumps back.
