vim - 普通模式下Control+空格vim键绑定(bind)不起作用

Question

我想将 control+space 映射到 :bnext 以便在正常模式下转发切换。所以我在我的 .vimrc 中添加了以下内容:

nnoremap <silent> <C-Space> :bn<CR>

对于后向搜索

nnoremap <silent> <C-S-Space> :bp<CR>

但是，此解决方案不起作用。关于问题是什么以及如何解决它的任何想法？

更新:我的映射列表:

n  [[          *@:call <SNR>45_Python_jump('?^\(class\|def\)')<CR>

我尝试时的缓冲区:

:ls
  1 #    "views.py"                     line 73
  2 %a   "./forms.py"                   line 19

什么原因导致问题？你能帮我吗？

Answer 1

在大多数终端中(我假设您正在使用，因为您没有指定 gVim/MacVim)，<C-Space>和 <C-S-Space>不要映射到实际的 ASCII 字符。您可以通过进入插入模式来确认这一点，输入 <C-V>启动文字字符插入，然后键入其中任何一个键。如果您看到 ^@这意味着您输入了无法映射到的 Null 字符。所以不幸的是，你要么需要切换到 Vim 的 GUI 风格(它确实理解非 ASCII 映射)，要么选择不同的映射。

编辑:我的错误，可以通过 <NUL> 映射空字符，正如另一个答案指出的那样。还是没有区别<C-S-Space>和 <C-Space> (或 <C-j> 和 <C-@> )，但您至少可以映射它们。
