The following command in vimrc works well for vim in my ubuntu os,
:map 11 :tabnext 1<CR>
,while in my CentOS system, i entered ’11’, it returns:

, i have to delete '<CR>', and then enter the “Enter” key to jump to tab 1;
All the ‘<CR>‘ in vimrc doesn’t work, it seems the vim can’t recognize ‘<BR>‘ as “Enter” KEY, anyone help me?
Try to replace <CR> with Ctrl + VEnter.
