I personally find it very awkward and unintuitive to browse the documentation using Ctrl-] for following the link and Ctrl-Shift-t to go back. I have had an idea to to remap those commands to Enter and Backspace, since I do not use those keys in help in normal mode.

The command :nnoremap <buffer> can remap the key only in the given buffer without affecting the other buffers.

Just create file $VIMRUNTIME/ftplugin/help.vim with following contens:

" Only do this when not done yet for this buffer
if exists("b:did_ftplugin")

" map ctrl-] to enter in normal mode only for this buffer
nnoremap <buffer><CR> <c-]>

" map ctrl-T to backspace in normal mode only for this buffer
nnoremap <buffer><BS> <c-T>


You can adapt this to also use it with the man page file type, so you can hit return on a ref to another man page etc.

I had to use the after config file "~/.vim/after/ftplugin/man.vim" and nmap instead of nnoremap to getting it working. (I think this is because the default man.vim needs to set its remap of <c-]> first.)

Very useful mappings for helpfiles. I've added them to my help.vim, which also contains these for navigating from |label| to |label|:

nnoremap <buffer> <Tab> /<Bar>\k*<Bar><CR>
nnoremap <buffer> <S-Tab> ?<Bar>\k*<Bar><CR>
" Can't get s-tab to work in xterm, so...
nmap <buffer> . <Tab>
nmap <buffer> , <S-Tab>

I couldn't get it working by using the help.vim file. Adding these lines to .vimrc seems to work though:

:au filetype help :nnoremap <buffer><CR> <c-]>
:au filetype help :nnoremap <buffer><BS> <c-T>

To avoid display of '|' when using goulding( mappings above, use theese instead:

nnoremap <buffer> <Tab> /<Bar>\zs\k*\ze<Bar><CR>
nnoremap <buffer> <S-Tab> ?<Bar>\zs\k*\ze<Bar><CR>

Also, don't put your mappings in $VIMRUNTIME/ftplugin/help.vim but instead in $HOME/{.vim|vimfiles}/after/ftplugin/help.vim (without the didftplugin check), as this will not completely override any ftplugin settings set by the Vim distribution either in this version or a next upgrade.

Here is my ~/.vim/after/ftplugin/help.vim and ~/.vim/after/ftplugin/man.vim (same content):

" Browse just with <CR>/<BS>
" We allow remapping of <C-]> as ftplugin/man.vim remaps it
nmap <buffer><CR> <C-]>
nnoremap <buffer><BS> <C-T>
if &filetype == 'help'
  " Lookup |label| using <Tab>/<S-Tab>
  nnoremap <buffer> <Tab> /<Bar>\zs\k*\ze<Bar><CR>
  nnoremap <buffer> <S-Tab> ?<Bar>\zs\k*\ze<Bar><CR>
