vim :: tags keyboard shortcuts

Keyboard shortcuts used to work with tags. There are really few of them. All of them work in control/normal mode.

• :set tags? needless to remind that VIM must be told which tag files to use. It can be done automatically as for example shown here.
  
• :tag word is main one. Opens file and goes to line with first tag entry matching word.
• ^] same as above, but uses word under cursor.
• :tag /word is similar to :tag word. Opens file and goes to line with first tag entry matching regular expression in word.
• :tselect word is what I use most often. The function - tag select - displays list of matching tags allowing you to select one to go to. Without word, it will display list of matching tags for word used last time.
  
• g^] same as above, but uses word under cursor. Also, omits displaying list if only single match is found.
• :tnext goes to next matching tag entry.
  
• :tprev goes to previous matching tag entry.
• :tlast goes to last matching tag entry.
• :tfirst goes to first matching tag entry.
• ^T Every time you do :tag word, the word with current file position is put on stack and vim goes to new file/position as it is told by tag file. To restore the previous file position you use ^T. The shortcut removes tag stack top element and moves to the file position saved there. So if you wandered off far away with ^] - to return back where you started you need to press ^T until vim would complain that it is at bottom of tag stack.
  

That's about it. Both :tag word and :tselect word support wildcard key (Tab/^D) to show list of tags matching partially the word. That will work with regilar expressions too. But be warned that often tag files can host millions of entries: displaying list of thousands items can take some time. Use wildcard key carefully.
