Mapping already in use: "<LocalLeader>sb", mode "n"

Question

I recently installed some plugins so I can use Vim as my development IDE. It appears some of the plugins are not playing nicely with each other.

Currently, I have the following vim plugins in my plugin directory:

• code_complete.vim
• cscope_maps.vim
• doxygen-support.vim
• sourcebeautify
• taglist.vim
• vcscommand.vim
• vcsgit.vim
• vcssvk.vim
• crefvim.vim
• c.vim
• minibufexpl.vim
• symfony.vim
• vcsbzr.vim
• vcscvs.vim
• vcshg.vim
• vcssvn.vim

My ~/.vimrc file has the following contents:

autocmd BufRead *.vala,*.vapi set efm=%f:%l.%c-%[%^:]%#:\ %t%[%^:]%#:\ %m
au BufRead,BufNewFile *.vala,*.vapi setfiletype vala

set nocp ts=4 sw=4 noet ai cin bs=2 cb=unnamed
set number ruler wrap autoread showcmd showmode fdm=marker nobackup
syntax on
filetype plugin on

set incsearch
set tags=./tags;/
map <C-\> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
map <A-]> :vsp <CR>:exec("tag ".expand("<cword>"))<CR>

When I attempt to open a C or C++ file, I get the following warning message:

Mapping already in use: "<LocalLeader>sb", mode "n"
Press Enter to Continue

Does anyone know which of the plugins is causing this, and how to resolve this issue?

Answer 1

:verbose map <LocalLeader>sb

this will show you which plugin(s) set that mapping
