I started using twitvim and found this code code for .vimrc.
But I am not sure what the last part of code is trying to do.
autocmd FileType twitvim call s:twitvim_my_settings()
function! s:twitvim_my_settings()
set nowrap
endfunction
And this is the original code. I deleted all of <C-u>, <C-w> and j.
""" twitvim
let twitvim_count = 40
nnoremap ,tp :<C-u>PosttoTwitter<CR>
nnoremap ,tf :<C-u>FriendsTwitter<CR><C-w>j
nnoremap ,tu :<C-u>UserTwitter<CR><C-w>j
nnoremap ,tr :<C-u>RepliesTwitter<CR><C-w>j
nnoremap ,tn :<C-u>NextTwitter<CR>
autocmd FileType twitvim call s:twitvim_my_settings()
function! s:twitvim_my_settings()
set nowrap
endfunction
