我正试图进入Vim并重新映射密钥等等，但我偶然发现了一个奇怪的问题。我把hjkl重新映射到了jkl；因为这对我来说更直观，但现在每当我按下；它向右移动了两次。我不确定我是否真的介意，因为这抵消了我的小指比其他手指弱的事实，但如果维姆忍者不介意通读这篇文章，我真的很想知道为什么会发生这种情况。
这是我的.virc（底部标记为Jae的Vim设置，摘录自我教授的一个Vim设置）：
" jj => esc
:imap jj <Esc>
"remap navigation keys
:nnoremap ; l
:nnoremap l k
:nnoremap k j
:nnoremap j h

" When coding, auto-indent by 4 spaces, just like in K&R

" You can do that with "set tabstop=4", which is a BAD idea

set expandtab
autocmd FileType make setlocal noexpandtab
" My settings when editing *.txt files
" - automatically indent lines according to previous lines
" - replace tab with 8 spaces
" - when I hit tab key, move 2 spaces instead of 8
" - wrap text if I go longer than 76 columns
" - check spelling
autocmd FileType text setlocal autoindent expandtab softtabstop=2 textwidth=76 spell spelllang=en_us
" Don't do spell-checking on Vim help files
autocmd FileType help setlocal nospell
" Prepend ~/.backup to backupdir so that Vim will look for that directory
" before littering the current dir with backups.
" You need to do "mkdir ~/.backup" for this to work.
set backupdir^=~/.backup
" Also use ~/.backup for swap files. The trailing // tells Vim to incorporate
" full path into swap file names.
set dir^=~/.backup//
" Ignore case when searching
" - override this setting by tacking on c or C to your search term to make
" your search always case-insensitive or case-sensitive, respectively.
set ignorecase

" End of Jae's Vim settings
问题是因为映射错误。您当前有
nnoremap ; l<space>
末端的额外空间被视为映射的一部分。由于默认情况下<space>向右移动，因此会导致移动两个空格。去掉多余的空间，它应该可以正常工作。
