I'm having some trouble reading vim's documentation on the terminal because I can't follow the links that are given.I quote:Jump to a subject:  Position the cursor on a tag (e.g. |bars|) and  hit CTRL-].The problem is that i'm using a spanish keyboard where the + and the ] are on the same button so when I hit CTRL-], I make a zoom.Can I map the CTRL-] to any other keys somehow or is there any other option?

One option (if you don't mind a bit of typing) is to type :tag tagname and press enter.  This is exactly equivalent to Ctrl-] according to :help CTRL-].If you use this, please note that you can use tab completion just as when typing :help topic commands, and you can use Ctrl-D to list the possible autocompletions of what you've typed so far.I admit this isn't much of an alternative, but it's worth knowing.
