Using TAB to jump thru help tags

2006-11-27 Thread DervishD
Hi all :)

First of all, please excuse if what I'm going to ask sounds
stupid, but I have been using vim for less than a week, so I'm afraid
I'm not very proficient with it ;)

Well, I've done this mapping to be able to jump to the next tag
in the help file using TAB:

:nnoremap silent buffer TAB /\|\S\+\|CR:nohlCRl

The problem is that when I hit TAB, the tags flash a bit,
because the search command highlight them and the :nohl turns hl
off. Moreover, this interferes with my searchs, if any.

What I want is to be able to do the above without interfering
with searches. I've been looking for a way of jumping into a pattern
without using search() or /, but I haven't found any. I've tried
:tag and friends, too, with no success :( I want to do this because
I'm spending a lot of time in the help right now, so I want a fast
way of jumping thru help tags.

Do anybody has any suggestion? Thanks a lot in advance :)

If you execute search() within a function, you won't lose the 
previous search pattern.  So you could do something like this.

function HelpTagSearch()
call search('|\S\+|')
endfunction

nmap silent buffer TAB :call HelpTagSearch()CR

See

:help :endf

and read the immediately-preceding paragraph.

Also note that | is not special in vim regular expressions, so it 
should not be escaped.

HTH,
Gary
