自己编写的键盘映射失灵，而且vim正在使用bash的热键，
导致我的vim现在的操作是这样的
插入模式下
ctrl-w 删除光标前的一个单词
ctrl-L 打出了^L
CTRL-J 换行

怎么才能正常配置使用键盘映射
我的vim有两个插件，youcompleteme,vundle
我的系统是ubuntu gnome

我自己的vimrc是这样

"基本设置
set nu
set tabstop=4
set bg=dark
set expandtab
set cursorline
set softtabstop=4
set hls
set shiftwidth=4
set fdm=syntax
set foldlevelstart=99
set autoindent
au filetype c,cpp set cindent
"键盘映射
map <S-Right> <Esc>:tabn<CR>
imap <S-Right> <Esc>:tabn<CR>i
map <S-Left>  <ESC>:tabp<CR>
imap <S-Left>  <ESC>:tabp<CR>i
map <C-o>     <Esc>:tabnew 
imap <C-o>     <Esc>:tabnew 
map <F5>      <Esc>:w<CR>:!g++ % -o %<<CR>
imap <F5>      <Esc>:w<CR>:!g++ % -o %<<CR>
map <C-F5>    <Esc>:w<CR>:!g++ % -o %< && ./%<<CR>

bash的配置文件我没有做任何更改
求问这个问题要怎么设置才能解决
